Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 325.79 g/mol gives 2-Chloro-3-((4-isopropylphenyl)amino)naphthalene-1,4-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Chloro-3-((4-isopropylphenyl)amino)naphthalene-1,4-dione (CAS 763130-56-9), a certified reference material (molecular formula C19H16ClNO2, MW 325.79 g/mol) for analytical method development and quality control.
2-Chloro-3-((4-isopropylphenyl)amino)naphthalene-1,4-dione (C19H16ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
