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 3-[(5Z)-4-Oxo-2-sulfanylidene-5-[(thiophen-2-yl)methylidene]-1,3-thiazolidin-3-yl]propanoic acid.
CATO supplies 3-[(5Z)-4-Oxo-2-sulfanylidene-5-[(thiophen-2-yl)methylidene]-1,3-thiazolidin-3-yl]propanoic acid (CAS 306279-31-2), a certified reference material (molecular formula C11H9NO3S3, MW 299.39 g/mol) for analytical method development and quality control.
3-[(5Z)-4-Oxo-2-sulfanylidene-5-[(thiophen-2-yl)methylidene]-1,3-thiazolidin-3-yl]propanoic acid (C11H9NO3S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-[(5Z)-4-Oxo-2-sulfanylidene-5-[(thiophen-2-yl)methylidene]-1,3-thiazolidin-3-yl]propanoic acid 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.
