Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Benzylideneamino)-2,5,6-trimethylthieno[2,3-d]pyrimidin-4(3H)-one.
3-(Benzylideneamino)-2,5,6-trimethylthieno[2,3-d]pyrimidin-4(3H)-one (CAS 331962-40-4) is a high-purity analytical reference standard with the molecular formula C16H15N3OS and a molecular weight of 297.37 g/mol.
3-(Benzylideneamino)-2,5,6-trimethylthieno[2,3-d]pyrimidin-4(3H)-one (C16H15N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
