Description
CATO manufactures 5-Chloro-2-(1H-1,2,4-triazol-1-yl)aniline 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.
5-Chloro-2-(1H-1,2,4-triazol-1-yl)aniline (CAS 450399-92-5) is a high-purity analytical reference standard with the molecular formula C8H7ClN4 and a molecular weight of 194.62 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-Chloro-2-(1H-1,2,4-triazol-1-yl)aniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
