Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-Chloro-2-(chloromethyl)-5,6,7,8-tetrahydro[1]benzothieno[2,3-d]pyrimidine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 273.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-Chloro-2-(chloromethyl)-5,6,7,8-tetrahydro[1]benzothieno[2,3-d]pyrimidine (CAS 88203-17-2) is a high-purity analytical reference standard with the molecular formula C11H10Cl2N2S and a molecular weight of 273.18 g/mol.
