2-Hexynoic acid, 5-methyl-, ethyl ester CAS 65236-42-2

Description

Compared with other compounds in its class, the molecular weight of 154.21 g/mol gives 2-Hexynoic acid, 5-methyl-, ethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Hexynoic acid, 5-methyl-, ethyl ester (CAS 65236-42-2), a certified reference material (molecular formula C9H14O2, MW 154.21 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Hexynoic acid, 5-methyl-, ethyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 2-Hexynoic acid, 5-methyl-, ethyl ester 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.
