Chemical Structure
Description
7-Bromo-1-butyl-1,2,3-benzotriazole-5-carbonitrile (CAS 1437794-90-5), molecular formula C11H11BrN4 and molecular weight 279.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Bromo-1-butyl-1,2,3-benzotriazole-5-carbonitrile (C11H11BrN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
