Chemical Structure

Polyphyllin Ii  CAS 76296-72-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 855.02 g/mol gives Polyphyllin Ii  distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Polyphyllin Ii  (CAS 76296-72-5), a certified reference material (molecular formula C44H70O16, MW 855.02 g/mol) for analytical method development and quality control.

The molecular framework of Polyphyllin Ii  (C44H70O16) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
