Description
As a certified reference material (CRM), 4-Acetylphenyl sulfate potassium salt 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.
4-Acetylphenyl sulfate potassium salt (CAS 38533-41-4) is a high-purity analytical reference standard with the molecular formula C8H7O5SK and a molecular weight of 254.30 g/mol.
4-Acetylphenyl sulfate potassium salt (C8H7O5SK) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
