Chemical Structure

Palatine Fast Black Wan CAS 5610-64-0 chemical structure

Description

Palatine Fast Black Wan (CAS 5610-64-0), molecular formula C20H10N3O7SCrNa and molecular weight 511.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Palatine Fast Black Wan (C20H10N3O7SCrNa) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
