Chemical Structure
Description
As a certified reference material (CRM), 2-Methyl-4-(p-tolyl)thiomorpholine-3,5-dione 1-oxide 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.
2-Methyl-4-(p-tolyl)thiomorpholine-3,5-dione 1-oxide (CAS 339097-19-7), molecular formula C12H13NO3S and molecular weight 251.30 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methyl-4-(p-tolyl)thiomorpholine-3,5-dione 1-oxide (C12H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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.
