Description

As a certified reference material (CRM), Methyl 3-((7-(4-chlorophenyl)-4-oxothieno[3,2-d]pyrimidin-3(4H)-yl)methyl)-4-methoxybenzoate 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.

Methyl 3-((7-(4-chlorophenyl)-4-oxothieno[3,2-d]pyrimidin-3(4H)-yl)methyl)-4-methoxybenzoate (CAS 1105223-62-8) is a high-purity analytical reference standard with the molecular formula C22H17ClN2O4S and a molecular weight of 440.90 g/mol.

Based on its molecular formula C22H17ClN2O4S, Methyl 3-((7-(4-chlorophenyl)-4-oxothieno[3,2-d]pyrimidin-3(4H)-yl)methyl)-4-methoxybenzoate contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 440.90 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
