Chemical Structure
Description
The occurrence of 5-(2-Chlorophenyl)-1H-tetrazole is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-(2-Chlorophenyl)-1H-tetrazole (CAS 50907-46-5), a certified reference material (molecular formula C7H5ClN4, MW 180.59 g/mol) for analytical method development and quality control.
The molecular framework of 5-(2-Chlorophenyl)-1H-tetrazole (C7H5ClN4) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 5-(2-Chlorophenyl)-1H-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.
