Chemical Structure

2-(5-Methoxy-1-tosyl-1H-indol-3-yl)ethan-1-ol CAS 936252-47-0 chemical structure

Description

2-(5-Methoxy-1-tosyl-1H-indol-3-yl)ethan-1-ol (CAS 936252-47-0), molecular formula C18H19NO4S and molecular weight 345.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(5-Methoxy-1-tosyl-1H-indol-3-yl)ethan-1-ol (C18H19NO4S) 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 2-(5-Methoxy-1-tosyl-1H-indol-3-yl)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.
