Chemical Structure

2-Aminobut-3-ynoic acid CAS 73410-55-6 chemical structure

Description

CATO supplies 2-Aminobut-3-ynoic acid (CAS 73410-55-6), a certified reference material (molecular formula C4H5NO2, MW 99.09 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Aminobut-3-ynoic acid is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 99.09 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.

As a certified reference material (CRM), 2-Aminobut-3-ynoic 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.
