Chemical Structure

Ethyl 4(Z),7(Z),10(Z),13(Z),16(Z)-docosapentaenoate CAS 142828-42-0 chemical structure

Description

Ethyl 4(Z),7(Z),10(Z),13(Z),16(Z)-docosapentaenoate (CAS 142828-42-0), molecular formula C24H38O2 and molecular weight 358.56 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 4(Z),7(Z),10(Z),13(Z),16(Z)-docosapentaenoate (C24H38O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 358.56 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
