Compared with other compounds in its class, the molecular weight of 210.25 g/mol gives 2-Methoxyphenylsulfate Potassium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Methoxyphenylsulfate Potassium Salt (CAS 3233-59-8), molecular formula C7H14O5S and molecular weight 210.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Methoxyphenylsulfate Potassium Salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
