With more than 30 years of experience in the synthesis, purification, and characterization of biochemicals, Cayman Chemical has become a leader in the field of designer drugs by providing high-purity reference standards to federally licensed laboratories and qualified academic research institutions for forensic analysis. Our highly trained staff of chemists provide institutions with solutions to quickly identify and understand the physiological and toxicological properties of new designer drugs. Cayman synthesizes a range of analytical standards including synthetic cannabinoids, cathinones, phenethylamines, amphetamines, indanes, opioids, benzodiazepines, tryptamines, and phytocannabinoids, among many others.
For institutions that rely on highly traceable reference standards for use in quantitative or qualitative testing, Cayman offers synthesized reference materials and certified reference materials accredited to meet ISO/IEC 17025:2005 and ISO Guide 34:2009 guidelines.
We are committed to ensuring and maintaining quality in all aspects of our certified reference material production.
Our quality management system is implemented and maintained by trained staff to meet the requirements set forth in ISO/IEC 17025 and ISO Guide 34. This quality management system is applicable to all staff and activities associated with the manufacture and testing of certified reference standards in our ISO-accredited laboratory.
Reference materials and certified reference materials will be accompanied by a Certificate of Analysis (COA), accredited to the requirements in ISO/IEC 17025:2005 and ISO Guide 34:2009.
The COA for the reference material will include purity information and a full characterization with spectra attached.
In addition to the values reported on the COA for the reference material, the COA for the certified reference material will also report a certified concentration and its uncertainty as well as homogeneity and long-term stability information.
ISO/IEC 17025:2005 meets the general requirements for the competence of testing and calibration laboratories. This ISO standard ensures Cayman is carrying out tests and calibrations to the highest degree of quality and reliability while characterizing Reference Materials (RMs) and certified Reference Materials (CRMs).
ISO Guide 34:2009 meets the general requirements for the competence of RM producers. This ISO standard recognizes Cayman for its competence in carrying out the standardized production, storage, and distribution of CRMs.

Cayman’s forensic product line is continually evolving. We are dedicated to working with the forensic and academic communities to identify emerging drugs of abuse and to quickly make authentic reference standards available from our ISO/IEC 17025:2005 and ISO Guide 34:2009 labs.
Cayman offers parent compounds as well as metabolites, isomers, deuterated standards, and DEA exempt reference standards. Custom mixtures are available upon request.
Certified Reference Materials (CRMs) serve as Primary Standards as defined by ISO and are suitable for labs requiring traceable quantitative standards. A CRM, as defined by ISO Guide 34:2009, must include a certified property value fully traceable to SI units as well as uncertainty. Cayman’s CRMs are suitable for accurately measuring concentrations of analytes in test samples and are sold as quantitative solutions in sealed ampules.
Cayman’s Reference Materials (RMs) are sold as neat solids in several sizes allowing for a low-cost, scalable, and highly-flexible option for analytical labs where accurate qualitative results are desired. An RM is fully characterized, and its property values are tested to ISO/IEC 17025:2005 guidelines, making it fit for direct use by labs requiring traceable qualitative standards.
