Description
CATO supplies 9-(3,4-Dichlorophenyl)-2,7-bis((dimethylamino)methyl)-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione dihydrobromide (CAS 118372-34-2), a certified reference material (molecular formula C25H30Cl2N2O3HBr, MW 558.34 g/mol) for analytical method development and quality control.
Structurally, 9-(3,4-Dichlorophenyl)-2,7-bis((dimethylamino)methyl)-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione dihydrobromide (C25H30Cl2N2O3HBr) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 558.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
