Description

As a certified reference material (CRM), (4R,6S)-6-Methyl-7,7-dioxido-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-yl acetate 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.

(4R,6S)-6-Methyl-7,7-dioxido-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-yl acetate (CAS 148810-82-6), molecular formula C10H12O4S2 and molecular weight 260.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (4R,6S)-6-Methyl-7,7-dioxido-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-yl acetate (C10H12O4S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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