3-Methyl-1-(4-methylphenyl)-1H-pyrazol-5-ol CAS 2046-03-9

Description

The occurrence of 3-Methyl-1-(4-methylphenyl)-1H-pyrazol-5-ol 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-Methyl-1-(4-methylphenyl)-1H-pyrazol-5-ol (CAS 2046-03-9), a certified reference material (molecular formula C11H12N2O, MW 188.23 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-Methyl-1-(4-methylphenyl)-1H-pyrazol-5-ol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 188.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3-Methyl-1-(4-methylphenyl)-1H-pyrazol-5-ol 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.
