Chemical Structure
Description
2-Tosyl-1H-benzo[d]imidazol-5-amine (CAS 1355151-93-7), molecular formula C14H13N3O2S and molecular weight 287.34 g/mol, is a CATO reference standard with documented purity and traceability.
2-Tosyl-1H-benzo[d]imidazol-5-amine (C14H13N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
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.
CATO manufactures 2-Tosyl-1H-benzo[d]imidazol-5-amine 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.
