Description

Compared with other compounds in its class, the molecular weight of 482.70 g/mol gives Naphthalenesulfonic acid, dinonyl-, sodium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Naphthalenesulfonic acid, dinonyl-, sodium salt (CAS 26834-28-6), molecular formula C28H43O3SNa and molecular weight 482.70 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Naphthalenesulfonic acid, dinonyl-, sodium salt (C28H43O3SNa) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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 482.70 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
