1-Cyclopropyl-3-(1,3-dimethyl-1H-pyrazol-4-yl)thiourea CAS 955892-61-2

Description

The occurrence of 1-Cyclopropyl-3-(1,3-dimethyl-1H-pyrazol-4-yl)thiourea is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Cyclopropyl-3-(1,3-dimethyl-1H-pyrazol-4-yl)thiourea (CAS 955892-61-2) is a high-purity analytical reference standard with the molecular formula C9H14N4S and a molecular weight of 210.30 g/mol.

The molecular framework of 1-Cyclopropyl-3-(1,3-dimethyl-1H-pyrazol-4-yl)thiourea (C9H14N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.

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.
