Diphenidol Hydrochloride CAS 3254-89-5

Description

Compared with other compounds in its class, the molecular weight of 345.91 g/mol gives Diphenidol Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diphenidol Hydrochloride (CAS 3254-89-5), molecular formula C21H27NOHCl and molecular weight 345.91 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Diphenidol Hydrochloride (C21H27NOHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 345.91 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.

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.
