1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole 2,2-dioxide CAS 96729-81-6

Description

The molecular framework of 1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole 2,2-dioxide (C11H11NO2S) 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 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).

1,3,4,5-Tetrahydrothiopyrano[4,3-b]indole 2,2-dioxide (CAS 96729-81-6) is a high-purity analytical reference standard with the molecular formula C11H11NO2S and a molecular weight of 221.28 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
