1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole-8-carboxylic acid CAS 94934-07-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 233.29 g/mol gives 1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole-8-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole-8-carboxylic acid (CAS 94934-07-3), molecular formula C12H11NO2S and molecular weight 233.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole-8-carboxylic acid (C12H11NO2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole-8-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.
