Description
CATO manufactures 6-((4-Bromophenyl)sulfonyl)pyridin-3-amine 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.
6-((4-Bromophenyl)sulfonyl)pyridin-3-amine (CAS 1221791-76-9), molecular formula C11H9BrN2O2S and molecular weight 313.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-((4-Bromophenyl)sulfonyl)pyridin-3-amine (C11H9BrN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
