Ethyl 3-(1-ethyl-3,5-dimethyl-1H-pyrazol-4-yl)propanoate CAS 956950-93-9 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 Ethyl 3-(1-ethyl-3,5-dimethyl-1H-pyrazol-4-yl)propanoate.

CATO supplies Ethyl 3-(1-ethyl-3,5-dimethyl-1H-pyrazol-4-yl)propanoate (CAS 956950-93-9), a certified reference material (molecular formula C12H20N2O2, MW 224.30 g/mol) for analytical method development and quality control.

Structurally, Ethyl 3-(1-ethyl-3,5-dimethyl-1H-pyrazol-4-yl)propanoate (C12H20N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 224.30 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 3-(1-ethyl-3,5-dimethyl-1H-pyrazol-4-yl)propanoate 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.
