5-Chloro-2-phenyl-2H-benzo[d][1,2,3]triazole CAS 118416-54-9

Description

Compared with other compounds in its class, the molecular weight of 229.67 g/mol gives 5-Chloro-2-phenyl-2H-benzo[d][1,2,3]triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-2-phenyl-2H-benzo[d][1,2,3]triazole (CAS 118416-54-9), molecular formula C12H8ClN3 and molecular weight 229.67 g/mol, is a CATO reference standard with documented purity and traceability.

5-Chloro-2-phenyl-2H-benzo[d][1,2,3]triazole (C12H8ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
