Chemical Structure
Description
The molecular framework of (5r)-5-Hydroxy-2,3,4,5-tetrahydro-1lambda6-benzothiepine-1,1-dione (C10H12O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
(5r)-5-Hydroxy-2,3,4,5-tetrahydro-1lambda6-benzothiepine-1,1-dione (CAS 1423040-77-0), molecular formula C10H12O3S and molecular weight 212.27 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (5r)-5-Hydroxy-2,3,4,5-tetrahydro-1lambda6-benzothiepine-1,1-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
