Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 598.57 g/mol gives ACID RED 106 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
ACID RED 106 (CAS 6844-74-2), molecular formula C23H17N3O9S3Na and molecular weight 598.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ACID RED 106 (C23H17N3O9S3Na) 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. 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.
