Chemical Structure
Description
The occurrence of 2,4-Dichloro-6-(vinylthio)-1,3,5-triazine is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4-Dichloro-6-(vinylthio)-1,3,5-triazine (CAS 667456-87-3) is a high-purity analytical reference standard with the molecular formula C5H3Cl2N3S and a molecular weight of 208.07 g/mol.
2,4-Dichloro-6-(vinylthio)-1,3,5-triazine (C5H3Cl2N3S) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
