Chemical Structure

12-cis-Heneicosenoic acid CAS 3515-84-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 324.54 g/mol gives 12-cis-Heneicosenoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 12-cis-Heneicosenoic acid (CAS 3515-84-2), a certified reference material (molecular formula C21H40O2, MW 324.54 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 12-cis-Heneicosenoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 12-cis-Heneicosenoic 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.
