Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 348.46 g/mol gives Methyl 2-{[2-(methylsulfanyl)thieno[3,2-d]pyrimidin-4-yl]sulfanyl}benzenecarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 2-{[2-(methylsulfanyl)thieno[3,2-d]pyrimidin-4-yl]sulfanyl}benzenecarboxylate (CAS 672951-72-3) is a high-purity analytical reference standard with the molecular formula C15H12N2O2S3 and a molecular weight of 348.46 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 2-{[2-(methylsulfanyl)thieno[3,2-d]pyrimidin-4-yl]sulfanyl}benzenecarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.46 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.
As a certified reference material (CRM), Methyl 2-{[2-(methylsulfanyl)thieno[3,2-d]pyrimidin-4-yl]sulfanyl}benzenecarboxylate 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.
