Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
5-Chloro-1-(4-methylphenyl)-1h-1,2,3,4-tetrazole (CAS 36951-51-6), molecular formula C8H7ClN4 and molecular weight 194.62 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-1-(4-methylphenyl)-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 5-Chloro-1-(4-methylphenyl)-1h-1,2,3,4-tetrazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
