Chemical Structure
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-(3-Methylbut-3-en-1-yl)-3-phenylthiourea (CAS 104741-27-7), molecular formula C12H16N2S and molecular weight 220.33 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Methylbut-3-en-1-yl)-3-phenylthiourea (C12H16N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
