2-(3-Chlorophenyl)-5-methyl-2H-1,2,3-triazol-4-amine CAS 1708400-87-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Chlorophenyl)-5-methyl-2H-1,2,3-triazol-4-amine.

2-(3-Chlorophenyl)-5-methyl-2H-1,2,3-triazol-4-amine (CAS 1708400-87-6), molecular formula C9H9ClN4 and molecular weight 208.65 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-(3-Chlorophenyl)-5-methyl-2H-1,2,3-triazol-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-Chlorophenyl)-5-methyl-2H-1,2,3-triazol-4-amine 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.
