Chemical Structure

1-(3,5-Dichlorophenyl)-4-(difluoromethyl)-1H-1,2,3-triazole CAS 916151-05-8 chemical structure

Description

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

CATO supplies 1-(3,5-Dichlorophenyl)-4-(difluoromethyl)-1H-1,2,3-triazole (CAS 916151-05-8), a certified reference material (molecular formula C9H5Cl2F2N3, MW 264.06 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-(3,5-Dichlorophenyl)-4-(difluoromethyl)-1H-1,2,3-triazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.06 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.

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), 1-(3,5-Dichlorophenyl)-4-(difluoromethyl)-1H-1,2,3-triazole 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.
