General description

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Docosahexaenoic Acid Ethyl Ester is the ethyl ester of docosahexaenoic acid, an essential omega-3 fatty acid.


This pharmaceutical secondary standard can also be used as follows:
  • Development and validation of a reverse phase high-performance liquid chromatography-tandem mass spectrometry (RP-HPLC-MS/MS)method to determine eicosapentaenoic acid and docosahexaenoic acid in their ethyl ester forms
  • Simulated moving bed (SMB) chromatographic separation of ethyl esters of eicosapentaenoic acid and docosahexaenoic acids

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
