Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 398.30 g/mol gives 3,8-Diamino-5-methyl-6-phenylphenanthridin-5-ium bromide hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,8-Diamino-5-methyl-6-phenylphenanthridin-5-ium bromide hydrate (CAS 37889-60-4), a certified reference material (molecular formula C20H18N3BrH2O, MW 398.30 g/mol) for analytical method development and quality control.
Structurally, 3,8-Diamino-5-methyl-6-phenylphenanthridin-5-ium bromide hydrate (C20H18N3BrH2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 398.30 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
