Ethyl (E)-3-(1-methyl-1H-pyrazol-5-yl)acrylate CAS 796845-48-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (E)-3-(1-methyl-1H-pyrazol-5-yl)acrylate.

Ethyl (E)-3-(1-methyl-1H-pyrazol-5-yl)acrylate (CAS 796845-48-2) is a high-purity analytical reference standard with the molecular formula C9H12N2O2 and a molecular weight of 180.20 g/mol.

Structurally, Ethyl (E)-3-(1-methyl-1H-pyrazol-5-yl)acrylate (C9H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 180.20 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ethyl (E)-3-(1-methyl-1H-pyrazol-5-yl)acrylate 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.
