Chemical Structure
Description
The molecular framework of 2-(3-Bromo-4-hydroxy-5-nitrophenyl)acetic acid (C8H6BrNO5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.
2-(3-Bromo-4-hydroxy-5-nitrophenyl)acetic acid (CAS 38694-44-9), molecular formula C8H6BrNO5 and molecular weight 276.04 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
