Compared with other compounds in its class, the molecular weight of 194.30 g/mol gives 1-Isopropyl-3-phenylthiourea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Isopropyl-3-phenylthiourea (CAS 15093-36-4) is a high-purity analytical reference standard with the molecular formula C10H14N2S and a molecular weight of 194.30 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1-Isopropyl-3-phenylthiourea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
