CATO supplies 1-(3,4-Dichlorophenyl)-5-(m-tolyl)-1H-tetrazole (CAS 338411-36-2), a certified reference material (molecular formula C14H10Cl2N4, MW 305.16 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-(3,4-Dichlorophenyl)-5-(m-tolyl)-1H-tetrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
