Description

Compared with other compounds in its class, the molecular weight of 348.52 g/mol gives 25532-45-0 methyl (19beta)-19-methyl-16,17-didehydro-18-oxayohimban-16-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 25532-45-0 methyl (19beta)-19-methyl-16,17-didehydro-18-oxayohimban-16-carboxylate (CAS 25532-45-0), a certified reference material (molecular formula C22H36O3, MW 348.52 g/mol) for analytical method development and quality control.

25532-45-0 methyl (19beta)-19-methyl-16,17-didehydro-18-oxayohimban-16-carboxylate (C22H36O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
