Chemical Structure
Description
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.
14-Hydroxy-3-methoxy-17-methyl-6-oxo-morphinan 6-Ethylene Ketal (1.0mg/ml in Acetonitrile) (CAS 21020-35-9), molecular formula C20H27NO4 and molecular weight 345.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 14-Hydroxy-3-methoxy-17-methyl-6-oxo-morphinan 6-Ethylene Ketal (1.0mg/ml in Acetonitrile) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.43 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).
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.
