Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((2,4-Dichlorophenyl)thio)-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide.
CATO supplies 4-((2,4-Dichlorophenyl)thio)-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide (CAS 339019-17-9), a certified reference material (molecular formula C13H10Cl2O2S3, MW 365.32 g/mol) for analytical method development and quality control.
The molecular framework of 4-((2,4-Dichlorophenyl)thio)-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide (C13H10Cl2O2S3) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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 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.
As a certified reference material (CRM), 4-((2,4-Dichlorophenyl)thio)-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide 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.
