Chemical Structure
Description
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.
CATO supplies 5-(2,6-Dichlorophenyl)-1H-tetrazole (CAS 50907-31-8), a certified reference material (molecular formula C7H5FN4, MW 164.14 g/mol) for analytical method development and quality control.
5-(2,6-Dichlorophenyl)-1H-tetrazole (C7H5FN4) contains a nitrile group, fluorine substitution, an aromatic ring system. 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.
