3,4,4-Trimethyl-1-phenyl-1H-pyrazol-5(4H)-one CAS 947-82-0

Description

The occurrence of 3,4,4-Trimethyl-1-phenyl-1H-pyrazol-5(4H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,4,4-Trimethyl-1-phenyl-1H-pyrazol-5(4H)-one (CAS 947-82-0), a certified reference material (molecular formula C12H14N2O, MW 202.25 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3,4,4-Trimethyl-1-phenyl-1H-pyrazol-5(4H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 202.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 3,4,4-Trimethyl-1-phenyl-1H-pyrazol-5(4H)-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.
