Chemical Structure
Description
CATO supplies 5-Bromo-3-nitro-thiophene-2-carboxylic Acid (CAS 101079-64-5), a certified reference material (molecular formula C5H2BrNO4S, MW 252.04 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-3-nitro-thiophene-2-carboxylic Acid (C5H2BrNO4S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Bromo-3-nitro-thiophene-2-carboxylic Acid 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.
