Chemical Structure

3,7-Bis(dimethylamino)phenothiazin-5-ium chloride mixt. with 3-(dimethylamino)-7-(methylamino)phenothiazin-5-ium chloride (1:1) 37247-10-2 Azure II CAS 37247-10-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 602.32 g/mol gives 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride mixt. with 3-(dimethylamino)-7-(methylamino)phenothiazin-5-ium chloride (1:1) 37247-10-2 Azure II distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,7-Bis(dimethylamino)phenothiazin-5-ium chloride mixt. with 3-(dimethylamino)-7-(methylamino)phenothiazin-5-ium chloride (1:1) 37247-10-2 Azure II (CAS 37247-10-2) is a high-purity analytical reference standard with the molecular formula C16H24N3SC15H22N3SCl and a molecular weight of 602.32 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride mixt. with 3-(dimethylamino)-7-(methylamino)phenothiazin-5-ium chloride (1:1) 37247-10-2 Azure II is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 602.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
