Ethyl 4-hydroxy-5-phenyl-1H-pyrazole-3-carboxylate CAS 34035-06-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-hydroxy-5-phenyl-1H-pyrazole-3-carboxylate.

Ethyl 4-hydroxy-5-phenyl-1H-pyrazole-3-carboxylate (CAS 34035-06-8), molecular formula C12H12N2O3 and molecular weight 232.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ethyl 4-hydroxy-5-phenyl-1H-pyrazole-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Ethyl 4-hydroxy-5-phenyl-1H-pyrazole-3-carboxylate 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.
