Compared with other compounds in its class, the molecular weight of 276.35 g/mol gives Potassium polymerized alkyl-naphthalene sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Potassium polymerized alkyl-naphthalene sulfonate (CAS 67828-14-2) is a high-purity analytical reference standard with the molecular formula C10H7O3SKCH2O and a molecular weight of 276.35 g/mol.
Structurally, Potassium polymerized alkyl-naphthalene sulfonate (C10H7O3SKCH2O) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 276.35 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
