Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-(Acridin-9-ylamino)-5-aminobenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3-(Acridin-9-ylamino)-5-aminobenzoic acid (CAS 655238-61-2), a certified reference material (molecular formula C20H15N3O2, MW 329.35 g/mol) for analytical method development and quality control.
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.
