Chemical Structure

2-(3-Butyn-1-yloxy)acetic acid CAS 121318-21-6 chemical structure

Description

2-(3-Butyn-1-yloxy)acetic acid (CAS 121318-21-6) is a high-purity analytical reference standard with the molecular formula C6H8O3 and a molecular weight of 128.13 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(3-Butyn-1-yloxy)acetic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.13 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-(3-Butyn-1-yloxy)acetic 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.
