4-CARBOXYBENZEDIAZONIUM TETRAFLUOROBORATE CAS 456-25-7 chemical structure

Description

CATO manufactures 4-CARBOXYBENZEDIAZONIUM TETRAFLUOROBORATE 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.

CATO supplies 4-CARBOXYBENZEDIAZONIUM TETRAFLUOROBORATE (CAS 456-25-7), a certified reference material (molecular formula C7H5N2O2BF4, MW 235.93 g/mol) for analytical method development and quality control.

The molecular framework of 4-CARBOXYBENZEDIAZONIUM TETRAFLUOROBORATE (C7H5N2O2BF4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. 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.
