Chemical Structure

Vat Red 1 CAS 3875-72-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 576.40 g/mol gives Vat Red 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Vat Red 1 (CAS 3875-72-7) is a high-purity analytical reference standard with the molecular formula C18H10Cl2O8S4Na and a molecular weight of 576.40 g/mol.

Vat Red 1 (C18H10Cl2O8S4Na) contains a salt form, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
