Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(3-Chlorophenyl)-1-methyl-1H-1,2,3,4-tetrazole.
CATO supplies 5-(3-Chlorophenyl)-1-methyl-1H-1,2,3,4-tetrazole (CAS 90278-24-3), a certified reference material (molecular formula C8H7ClN4, MW 194.62 g/mol) for analytical method development and quality control.
5-(3-Chlorophenyl)-1-methyl-1H-1,2,3,4-tetrazole (C8H7ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
