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 Methyl 8-chloro-4H-thieno[3,2-c]thiochromene-2-carboxylate.
CATO supplies Methyl 8-chloro-4H-thieno[3,2-c]thiochromene-2-carboxylate (CAS 255378-11-1), a certified reference material (molecular formula C13H9ClO2S2, MW 296.79 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 8-chloro-4H-thieno[3,2-c]thiochromene-2-carboxylate (C13H9ClO2S2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Methyl 8-chloro-4H-thieno[3,2-c]thiochromene-2-carboxylate 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.
