Chemical Structure

5-Bromo-2-ethyl-2H-1,2,3-triazole-4-carbaldehyde CAS 2309458-30-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-2-ethyl-2H-1,2,3-triazole-4-carbaldehyde.

CATO supplies 5-Bromo-2-ethyl-2H-1,2,3-triazole-4-carbaldehyde (CAS 2309458-30-6), a certified reference material (molecular formula C5H6BrN3O, MW 204.02 g/mol) for analytical method development and quality control.

The molecular framework of 5-Bromo-2-ethyl-2H-1,2,3-triazole-4-carbaldehyde (C5H6BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
