Chemical Structure
Description
4,4',4''-Nitrilotri(benzohydrazide) (CAS 223591-21-7), molecular formula C21H21N7O3 and molecular weight 419.44 g/mol, is a CATO reference standard with documented purity and traceability.
4,4',4''-Nitrilotri(benzohydrazide) (C21H21N7O3) contains a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4,4',4''-Nitrilotri(benzohydrazide) 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.
