Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4R,6S)-6-Methyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-ol.
CATO supplies (4R,6S)-6-Methyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-ol (CAS 147086-80-4), a certified reference material (molecular formula C8H10OS2, MW 186.29 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, (4R,6S)-6-Methyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (4R,6S)-6-Methyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-ol 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.
