Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
6-(((4,6-Dimethylpyrimidin-2-yl)thio)methyl)-4-oxo-4H-pyran-3-yl 2-chlorobenzoate (CAS 877635-63-7) is a high-purity analytical reference standard with the molecular formula C19H15ClN2O4S and a molecular weight of 402.85 g/mol.
6-(((4,6-Dimethylpyrimidin-2-yl)thio)methyl)-4-oxo-4H-pyran-3-yl 2-chlorobenzoate (C19H15ClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
