Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2Z)-1-{1-[4-(2,4-dichlorophenyl)-1,3-thiazol-2-yl]-5-hydroxy-3-methyl-1H-pyrazol-4-yl}-3-hydroxybut-2-en-1-one.
CATO supplies (2Z)-1-{1-[4-(2,4-dichlorophenyl)-1,3-thiazol-2-yl]-5-hydroxy-3-methyl-1H-pyrazol-4-yl}-3-hydroxybut-2-en-1-one (CAS 245039-17-2), a certified reference material (molecular formula C17H13Cl2N3O3S, MW 410.27 g/mol) for analytical method development and quality control.
(2Z)-1-{1-[4-(2,4-dichlorophenyl)-1,3-thiazol-2-yl]-5-hydroxy-3-methyl-1H-pyrazol-4-yl}-3-hydroxybut-2-en-1-one (C17H13Cl2N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), (2Z)-1-{1-[4-(2,4-dichlorophenyl)-1,3-thiazol-2-yl]-5-hydroxy-3-methyl-1H-pyrazol-4-yl}-3-hydroxybut-2-en-1-one 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.
