Chemical Structure
Description
As a certified reference material (CRM), 1-[(4-chlorophenyl)methyl]-1h-1,2,4-triazol-3-amine 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.
CATO supplies 1-[(4-chlorophenyl)methyl]-1h-1,2,4-triazol-3-amine (CAS 147159-33-9), a certified reference material (molecular formula C9H9ClN4, MW 208.65 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-[(4-chlorophenyl)methyl]-1h-1,2,4-triazol-3-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. 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.
