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 (Z)-EThyl 2-(2-(5-(1-methyl-4-ethoxycarbonyl-1h-pyrazole))hydrazono)-2-chloroacetate.
(Z)-EThyl 2-(2-(5-(1-methyl-4-ethoxycarbonyl-1h-pyrazole))hydrazono)-2-chloroacetate (CAS 1207062-34-7), molecular formula C11H15ClN4O4 and molecular weight 302.71 g/mol, is a CATO reference standard with documented purity and traceability.
(Z)-EThyl 2-(2-(5-(1-methyl-4-ethoxycarbonyl-1h-pyrazole))hydrazono)-2-chloroacetate (C11H15ClN4O4) contains a nitrogen-containing heterocyclic scaffold, an amide 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. 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.
As a certified reference material (CRM), (Z)-EThyl 2-(2-(5-(1-methyl-4-ethoxycarbonyl-1h-pyrazole))hydrazono)-2-chloroacetate 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.
