Chemical Structure
Description
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.
2,4,6-Trichloro-5-(methylthio)pyrimidine (CAS 24795-76-4) is a high-purity analytical reference standard with the molecular formula C5H3Cl3N2S and a molecular weight of 229.51 g/mol.
Structurally, 2,4,6-Trichloro-5-(methylthio)pyrimidine (C5H3Cl3N2S) contains a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 229.51 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
