Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-BRomo-4-fluoro-2-nitro-phenyl)-hydrazine.
(5-BRomo-4-fluoro-2-nitro-phenyl)-hydrazine (CAS 1217303-75-7), molecular formula C6H5BrFN3O2 and molecular weight 250.03 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-BRomo-4-fluoro-2-nitro-phenyl)-hydrazine (C6H5BrFN3O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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.
CATO manufactures (5-BRomo-4-fluoro-2-nitro-phenyl)-hydrazine 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.
