Chemical Structure
Description
The occurrence of 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile (CAS 33097-13-1), a certified reference material (molecular formula C6H3Cl2N3S, MW 220.08 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
