Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1-(2-Chlorophenyl)-2-(trimethylsilyl)ethyl)-1H-benzo[d][1,2,3]triazole.
1-(1-(2-Chlorophenyl)-2-(trimethylsilyl)ethyl)-1H-benzo[d][1,2,3]triazole (CAS 196861-96-8), molecular formula C17H20ClN3Si and molecular weight 329.90 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-(1-(2-Chlorophenyl)-2-(trimethylsilyl)ethyl)-1H-benzo[d][1,2,3]triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.90 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-(1-(2-Chlorophenyl)-2-(trimethylsilyl)ethyl)-1H-benzo[d][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.
