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 Ethyl 2-amino-6,6-dioxo-4h,5h,7h-6λ6-thieno[2,3-c]thiopyran-3-carboxylate.
CATO supplies Ethyl 2-amino-6,6-dioxo-4h,5h,7h-6λ6-thieno[2,3-c]thiopyran-3-carboxylate (CAS 474843-59-9), a certified reference material (molecular formula C10H13NO4S2, MW 275.34 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-amino-6,6-dioxo-4h,5h,7h-6λ6-thieno[2,3-c]thiopyran-3-carboxylate (C10H13NO4S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl 2-amino-6,6-dioxo-4h,5h,7h-6λ6-thieno[2,3-c]thiopyran-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
