Chemical Structure

Sodium 6,13-dichloro-3,10-bis(phenylamino)benzo[5,6][1,4]oxazino[2,3-b]phenoxazine-2,9-disulfonate CAS 6527-70-4 chemical structure

Description

The occurrence of Sodium 6,13-dichloro-3,10-bis(phenylamino)benzo[5,6][1,4]oxazino[2,3-b]phenoxazine-2,9-disulfonate is closely related to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium 6,13-dichloro-3,10-bis(phenylamino)benzo[5,6][1,4]oxazino[2,3-b]phenoxazine-2,9-disulfonate (CAS 6527-70-4) is a high-purity analytical reference standard with the molecular formula C30H16Cl2N4O8S2Na and a molecular weight of 718.49 g/mol.

The molecular framework of Sodium 6,13-dichloro-3,10-bis(phenylamino)benzo[5,6][1,4]oxazino[2,3-b]phenoxazine-2,9-disulfonate (C30H16Cl2N4O8S2Na) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
