Description

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.

2-({4-[(e)-(3-methyl-4-{[(4-methylphenyl)sulfonyl]oxy}phenyl)diazenyl]phenyl}amino)-5-nitrobenzenesulfonic acid 99569-11-6 AR-1C5916 (CAS 99569-11-6), molecular formula C4H8O3 and molecular weight 104.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-({4-[(e)-(3-methyl-4-{[(4-methylphenyl)sulfonyl]oxy}phenyl)diazenyl]phenyl}amino)-5-nitrobenzenesulfonic acid 99569-11-6 AR-1C5916 (C4H8O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
