Chemical Structure
Description
2-((3-Aminophenyl)sulfonyl)ethan-1-ol (CAS 5246-57-1), molecular formula C8H11NO3S and molecular weight 201.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((3-Aminophenyl)sulfonyl)ethan-1-ol (C8H11NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 2-((3-Aminophenyl)sulfonyl)ethan-1-ol 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.
