Benzenesulfonic acid, oxybis[decyl-, sodium salt CAS 70146-13-3

Description

Compared with other compounds in its class, the molecular weight of 631.84 g/mol gives Benzenesulfonic acid, oxybis[decyl-, sodium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Benzenesulfonic acid, oxybis[decyl-, sodium salt (CAS 70146-13-3), molecular formula C32H48O7S2Na and molecular weight 631.84 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, a polycyclic aromatic system, Benzenesulfonic acid, oxybis[decyl-, sodium salt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 631.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
