4-Methyl-1-(thiophen-2-ylmethyl)-1h-pyrazol-3-amine CAS 1342844-88-5

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Methyl-1-(thiophen-2-ylmethyl)-1h-pyrazol-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.27 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).

4-Methyl-1-(thiophen-2-ylmethyl)-1h-pyrazol-3-amine (CAS 1342844-88-5), molecular formula C9H11N3S and molecular weight 193.27 g/mol, is a CATO reference standard with documented purity and traceability.

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.
