Chemical Structure

4-Chloro-2-styryl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine CAS 101130-32-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 326.84 g/mol gives 4-Chloro-2-styryl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-2-styryl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine (CAS 101130-32-9) is a high-purity analytical reference standard with the molecular formula C18H15ClN2S and a molecular weight of 326.84 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-Chloro-2-styryl-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.84 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
