Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5E)-5-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)methylidene]-2-(methylsulfanyl)-4,5-dihydro-1,3-thiazol-4-one.
CATO supplies (5E)-5-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)methylidene]-2-(methylsulfanyl)-4,5-dihydro-1,3-thiazol-4-one (CAS 956188-14-0), a certified reference material (molecular formula C10H10ClN3OS2, MW 287.79 g/mol) for analytical method development and quality control.
(5E)-5-[(5-Chloro-1,3-dimethyl-1H-pyrazol-4-yl)methylidene]-2-(methylsulfanyl)-4,5-dihydro-1,3-thiazol-4-one (C10H10ClN3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
