1-Methyl-N-(1-(5-methylthiophen-2-yl)ethyl)-1h-pyrazol-3-amine CAS 1179963-99-5

Description

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.

1-Methyl-N-(1-(5-methylthiophen-2-yl)ethyl)-1h-pyrazol-3-amine (CAS 1179963-99-5), molecular formula C11H15N3S and molecular weight 221.32 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H15N3S, 1-Methyl-N-(1-(5-methylthiophen-2-yl)ethyl)-1h-pyrazol-3-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
