Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 522.62 g/mol gives (R)-5-Methyl-3-(morpholinomethyl)-6-(1-naphthylcarbonyl)-2,3-dihydro-[1,4]oxazino[2,3,4-hi]indole Methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-5-Methyl-3-(morpholinomethyl)-6-(1-naphthylcarbonyl)-2,3-dihydro-[1,4]oxazino[2,3,4-hi]indole Methanesulfonate (CAS 131543-23-2), molecular formula C27H26N2O3CH4O3S and molecular weight 522.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (R)-5-Methyl-3-(morpholinomethyl)-6-(1-naphthylcarbonyl)-2,3-dihydro-[1,4]oxazino[2,3,4-hi]indole Methanesulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 522.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
