2-(phenothiazin-3-ylideneamino)benzene-1,4-disulfonic acid CAS 178861-30-8

Description

The occurrence of 2-(phenothiazin-3-ylideneamino)benzene-1,4-disulfonic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(phenothiazin-3-ylideneamino)benzene-1,4-disulfonic acid (CAS 178861-30-8) is a high-purity analytical reference standard with the molecular formula C18H12N2O6S3 and a molecular weight of 448.49 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(phenothiazin-3-ylideneamino)benzene-1,4-disulfonic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 448.49 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).

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.
