Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Amino-5-methyl-1H-pyrazol-4-yl)thiazol-4(5H)-one.

2-(3-Amino-5-methyl-1H-pyrazol-4-yl)thiazol-4(5H)-one (CAS 141763-70-4) is a high-purity analytical reference standard with the molecular formula C7H8N4OS and a molecular weight of 196.23 g/mol.

Based on its molecular formula C7H8N4OS, 2-(3-Amino-5-methyl-1H-pyrazol-4-yl)thiazol-4(5H)-one contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 196.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
