Chemical Structure

3-(4-Methyl-1h-pyrazol-1-yl)propanethioamide CAS 1183346-49-7 chemical structure

Description

The molecular framework of 3-(4-Methyl-1h-pyrazol-1-yl)propanethioamide (C7H11N3S) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 3-(4-Methyl-1h-pyrazol-1-yl)propanethioamide (CAS 1183346-49-7), a certified reference material (molecular formula C7H11N3S, MW 169.25 g/mol) for analytical method development and quality control.

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.

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.
