2-[(diethylamino)methyl]-5,6-dimethylthieno[2,3-d]pyrimidine-4-thiol CAS 855991-74-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[(diethylamino)methyl]-5,6-dimethylthieno[2,3-d]pyrimidine-4-thiol.

2-[(diethylamino)methyl]-5,6-dimethylthieno[2,3-d]pyrimidine-4-thiol (CAS 855991-74-1) is a high-purity analytical reference standard with the molecular formula C13H19N3S2 and a molecular weight of 281.44 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-[(diethylamino)methyl]-5,6-dimethylthieno[2,3-d]pyrimidine-4-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.44 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.
