At J&K we take pride in our role as a global leader in the chemical supply industry. We deliver only the finest quality products, and we do so in a way that allows us to maximize our contribution to people, private industry and society, both today and in the years to come.

Our manufacturing facilities and processes are state-of-the-art. With highly flexible and modern production lines, we are able to expertly perform a wide range of scientific experiments and production tasks including those that are anhydrous, oxygen-free, ultra-low temperature, and high pressure. We offer reliable and accurate continuous manufacturing of various types of complex compounds in sizes that can range from grams to kilograms and tons.

J&K’s quality management assurance programs include comprehensive quality control measures (e.g. NMR, LC-MS, GC-MS, FT-IR, HPLC and other advanced detection methods) at all steps of our process, from raw materials, to production, to the final product. We are ISO9000 certified.

J&K Quality Policy

We are living in an era when great challenges face humanity. Resource depletion and climate change threaten our way of life. An aging population faces new and growing health crises. World population growth places extreme demands on our water, energy and food supplies. As the world faces these many challenges, J&K Scientific is ideally positioned to be part of the solution.

Environmental Sustainability

We understand that our commitment to quality must include using resources efficiently and responsibly. We are constantly working to reduce energy use in our business operations, to eliminate waste in our manufacturing processes and packaging, and to increase our Green Chemistry product line with J&K Green Reagents that reduce harmful by-products in a wide range of chemical processes.

Our environmental commitment in our production facilities goes beyond simply establishing documents of environmental protection in accordance with relevant government laws and regulations. We have made significant capital investments in gas column leaching, sewage treatment, chemical waste processing and other environmental processing facilities. We remain dedicated to the principles of sustainable development and to an ongoing process of reducing both the direct and indirect environmental footprint of our business activities.

Shipping Conditions

There are some environmental conditions that may not be advised for long-term storage but will not affect product quality during short-term exposure. In such cases, J&K will ship at ambient temperature. Products will be shipped on ice when they are sensitive to environmental conditions during short-term exposure. Customers can request special shipping/handling conditions, but such shipping/handling is at customer expense if our experience indicates that the product is stable for regular shipment.

Recommended Long-Term Storage

Long-term storage conditions should follow the instructions on the J&K Product label. Recommended long-term storage is indicated in J&K Product Labels as follows:


Products that are labeled for Ambient storage or that have no storage recommendation may be stored under ambient temperature conditions. These products should not be exposed to direct sunlight.


Products that are labeled for Refrigerator storage should be stored at temperatures between 2 to 8°C.


Products that are labeled for Freezer storage will typically indicate a storage temperature of -20°C. It is acceptable to store these products in an environment that is thermostatically temperature controlled between -15 to -25°C.

Product Documentation

Product specifications about most J&K products can be found on the Product Label and/or J&K website and/or batch Certificate of Analysis.

Certificate of Analysis (COA)

The Certificate of Analysis includes the following information:

• Catalog No.
• Lot Number
• Product Name
• CAS number
• Version
• Formula & Formula Weight
• Issue Date
• Analytical Test Results
• Authorization Signature (from the site that released the batch)

Container Label

The Container Label includes the following information:

• Product Name
• Product and Batch Number
• Physical Chemical Properties
• Storage and Handling Information (Recommended Long-term Storage)
Risk & Safety Statements (multiple languages with pictograms)

Sample Retention

J&K makes every effort to retain sample quantities of material for testing. Sample availability will vary depending upon the product and/or batch. Certain products may have retained material from batches no longer available. Please contact your local J&K Customer Service Department to learn specific information about sample material availability.

Quality Assurance & Quality Control

J&K has established policies and procedures to ensure Product Quality.

Process & Specification Control


Standard Operating Procedures direct product production processes and define testing protocols for final products.

Quality Records

J&K uses a strict product and batch numbering and tracking system so that information records relating to all parts of a product lifecycle (from raw material to final quality analysis) can be retrieved as needed. Records are maintained and available according to Good Manufacturing Practice (GMP).


All critical equipment is calibrated and tested on a defined regular schedule to ensure reliability.


A vital component of J&K’s quality control of our processes is the protocol to address a batch that is determined to be nonconforming to product specifications. Such a batch is "flagged" electronically to prevent sales and shipment. The batch may also be physically labeled and/or segregated to clearly indicate that it is not to be sold or shipped to customers.

Purchasing Materials and Outer Packaging Material

When materials are received from our suppliers, we review Certificates of Analysis. If warranted, purchased materials may also pass through a physical quality inspection and review process. Materials will be maintained in a "Quarantined" status until the review is complete. We have also established strict quality standards for outer packaging materials to ensure product quality.

Chemical Intermediates

For critical intermediate processes, parameter controls and test indicators are used.

Final Product

All batches are tested to ensure that final products conform to the stringent standards of J&K’s Product Specification System.

Analysis and Testing

J&K uses a wide range of analytical and testing methods to assure Quality Control. All J&K personnel involved in Quality Analysis and Testing have relevant academic qualifications to at least a Bachelor’s degree level. Over 25% of those staff also have relevant Masters’ degrees. Our internal staff training and development programs address both universal and job specific requirements.

Analytical Methods:

J&K uses Analytical Methods that have been established for the majority of our products based upon specific product characteristics and by comparing the best practices and outcomes of different available methods.

Result Verification:

J&K has well-established verification procedures. All analytical results are verified by two different independent Quality Control staff. Any nonconforming results are investigated according to defined standardized procedures.

Please contact your local J&K Customer Service Department to learn specific information about our Analysis and Testing methods and procedures.
