Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(7Z,10Z,13Z,16Z,19Z)-Docosa-7,10,13,16,19-pentaen-4-ynoic acid (CAS 660429-97-0) is a high-purity analytical reference standard with the molecular formula C22H30O2 and a molecular weight of 326.47 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, (7Z,10Z,13Z,16Z,19Z)-Docosa-7,10,13,16,19-pentaen-4-ynoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (7Z,10Z,13Z,16Z,19Z)-Docosa-7,10,13,16,19-pentaen-4-ynoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
