Chemical Structure

2-(Prop-2-yn-1-yl)pent-4-ynoic acid CAS 65994-70-9 chemical structure

Description

CATO manufactures 2-(Prop-2-yn-1-yl)pent-4-ynoic 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.

2-(Prop-2-yn-1-yl)pent-4-ynoic acid (CAS 65994-70-9), molecular formula C8H8O2 and molecular weight 136.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-(Prop-2-yn-1-yl)pent-4-ynoic acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.15 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.
