Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Thioxo-1-(o-tolyl)pyrrolidin-2-one.
5-Thioxo-1-(o-tolyl)pyrrolidin-2-one (CAS 96933-17-4), molecular formula C11H11NOS and molecular weight 205.28 g/mol, is a CATO reference standard with documented purity and traceability.
5-Thioxo-1-(o-tolyl)pyrrolidin-2-one (C11H11NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 5-Thioxo-1-(o-tolyl)pyrrolidin-2-one 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.
