Icosa-5,7-diynoic acid CAS 69288-29-5 chemical structure

Description

CATO manufactures Icosa-5,7-diynoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Icosa-5,7-diynoic acid (CAS 69288-29-5), a certified reference material (molecular formula C20H32O2, MW 304.47 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, Icosa-5,7-diynoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.47 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).

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