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-(2,3-Dihydro-indole-1-sulfonyl)-2-methoxy-benzoic acid.
5-(2,3-Dihydro-indole-1-sulfonyl)-2-methoxy-benzoic acid (CAS 170287-67-9) is a high-purity analytical reference standard with the molecular formula C16H15NO5S and a molecular weight of 333.36 g/mol.
The molecular framework of 5-(2,3-Dihydro-indole-1-sulfonyl)-2-methoxy-benzoic acid (C16H15NO5S) is characterized by a flavonoid core, 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 5-(2,3-Dihydro-indole-1-sulfonyl)-2-methoxy-benzoic 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.
