Chemical Structure

4,6-Dichloro-2-methylsulfanyl-pyrimidine 4,6-Dichloropyrimidine methyl sulphide 4,6-Dichloro-2-methylmercaptopyrimidine 4,6-Dichloro-2-methylthiopyrimidine 6299-25-8 CAS 6299-25-8 chemical structure

Description

The molecular framework of 4,6-Dichloro-2-methylsulfanyl-pyrimidine 4,6-Dichloropyrimidine methyl sulphide 4,6-Dichloro-2-methylmercaptopyrimidine 4,6-Dichloro-2-methylthiopyrimidine 6299-25-8 (C5H10Cl2N2S) is characterized by sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

4,6-Dichloro-2-methylsulfanyl-pyrimidine 4,6-Dichloropyrimidine methyl sulphide 4,6-Dichloro-2-methylmercaptopyrimidine 4,6-Dichloro-2-methylthiopyrimidine 6299-25-8 (CAS 6299-25-8), molecular formula C5H10Cl2N2S and molecular weight 201.12 g/mol, is a CATO reference standard with documented purity and traceability.
