Compared with other compounds in its class, the molecular weight of 425.47 g/mol gives rac N,O-Didesmethyl Venlafaxine -D-Glucuronide Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
rac N,O-Didesmethyl Venlafaxine -D-Glucuronide Hydrochloride (CAS 1021933-99-2), molecular formula C21H31NO8 and molecular weight 425.47 g/mol, is a CATO reference standard with documented purity and traceability.
rac N,O-Didesmethyl Venlafaxine -D-Glucuronide Hydrochloride (C21H31NO8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
