Description
CATO supplies 3,5-Dimethyl-1-(prop-2-yn-1-yl)-1h-1,2,4-triazole hydrochloride (CAS 1311315-31-7), a certified reference material (molecular formula C7H9N3HCl, MW 171.63 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 3,5-Dimethyl-1-(prop-2-yn-1-yl)-1h-1,2,4-triazole hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.63 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.
As a certified reference material (CRM), 3,5-Dimethyl-1-(prop-2-yn-1-yl)-1h-1,2,4-triazole hydrochloride 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.
