Description
Compared with other compounds in its class, the molecular weight of 330.77 g/mol gives 1,4-Diamino-7-chloro-2-propoxyanthracene-9,10-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,4-Diamino-7-chloro-2-propoxyanthracene-9,10-dione (CAS 88605-47-4), a certified reference material (molecular formula C17H15ClN2O3, MW 330.77 g/mol) for analytical method development and quality control.
1,4-Diamino-7-chloro-2-propoxyanthracene-9,10-dione (C17H15ClN2O3) contains a steroid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
