Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Dihydroxypropyl 2-((7-chloroquinolin-4-yl)amino)benzoate hydrochloride.
2,3-Dihydroxypropyl 2-((7-chloroquinolin-4-yl)amino)benzoate hydrochloride (CAS 65513-72-6), molecular formula C19H17ClN2O4HCl and molecular weight 409.26 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dihydroxypropyl 2-((7-chloroquinolin-4-yl)amino)benzoate hydrochloride (C19H17ClN2O4HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
