Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.67 g/mol gives 1-Amino-8-chloroanthracene-9,10-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Amino-8-chloroanthracene-9,10-dione (CAS 117-09-9), a certified reference material (molecular formula C14H8ClNO2, MW 257.67 g/mol) for analytical method development and quality control.
1-Amino-8-chloroanthracene-9,10-dione (C14H8ClNO2) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
