4-chloro-5,6-dimethyl-2-[(methylsulfanyl)methyl]thieno[2,3-d]pyrimidine (CAS 885460-27-5) is a high-purity analytical reference standard with the molecular formula C10H19ClN2S2 and a molecular weight of 266.85 g/mol.
The molecular framework of 4-chloro-5,6-dimethyl-2-[(methylsulfanyl)methyl]thieno[2,3-d]pyrimidine (C10H19ClN2S2) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 4-chloro-5,6-dimethyl-2-[(methylsulfanyl)methyl]thieno[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
