Chemical Structure
Description
CATO supplies 2-(4-Ethylphenyl)-6-methyl-2H-1,2,3-benzotriazol-5-amine (CAS 443291-79-0), a certified reference material (molecular formula C15H16N4, MW 252.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H16N4, 2-(4-Ethylphenyl)-6-methyl-2H-1,2,3-benzotriazol-5-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
