Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1797131-45-3 3-Chloro-1-(1H-1,2,4-triazol-1-yl)-propan-2-one.

1797131-45-3 3-Chloro-1-(1H-1,2,4-triazol-1-yl)-propan-2-one (CAS 1797131-45-3), molecular formula C5H6ClN3O and molecular weight 159.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1797131-45-3 3-Chloro-1-(1H-1,2,4-triazol-1-yl)-propan-2-one (C5H6ClN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
