3-Methyl-4-(p-tolyl)-1h-pyrazol-5-amine CAS 1159187-59-3

Description

The occurrence of 3-Methyl-4-(p-tolyl)-1h-pyrazol-5-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Methyl-4-(p-tolyl)-1h-pyrazol-5-amine (CAS 1159187-59-3), molecular formula C11H13N3 and molecular weight 187.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-Methyl-4-(p-tolyl)-1h-pyrazol-5-amine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 187.24 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).

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-4-(p-tolyl)-1h-pyrazol-5-amine 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.
