1-(1H-1,2,3-triazol-4-yl)ethan-1-one hydrochloride CAS 1864052-48-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1H-1,2,3-triazol-4-yl)ethan-1-one hydrochloride.

CATO supplies 1-(1H-1,2,3-triazol-4-yl)ethan-1-one hydrochloride (CAS 1864052-48-1), a certified reference material (molecular formula C4H5N3OHCl, MW 147.56 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(1H-1,2,3-triazol-4-yl)ethan-1-one hydrochloride is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.56 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), 1-(1H-1,2,3-triazol-4-yl)ethan-1-one hydrochloride 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.
