Ethyl (7Z,10Z,13Z,16Z)-docosa-7,10,13,16-tetraenoate CAS 142828-41-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (7Z,10Z,13Z,16Z)-docosa-7,10,13,16-tetraenoate.

Ethyl (7Z,10Z,13Z,16Z)-docosa-7,10,13,16-tetraenoate (CAS 142828-41-9), molecular formula C24H40O2 and molecular weight 360.57 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl (7Z,10Z,13Z,16Z)-docosa-7,10,13,16-tetraenoate (C24H40O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
