4-Formylbenzene-1,3-disulfonic acid CAS 88-39-1

Description

The occurrence of 4-Formylbenzene-1,3-disulfonic acid is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Formylbenzene-1,3-disulfonic acid (CAS 88-39-1), a certified reference material (molecular formula C7H6O7S2, MW 266.25 g/mol) for analytical method development and quality control.

4-Formylbenzene-1,3-disulfonic acid (C7H6O7S2) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
