Paricalcitol Impurity 11 CAS 95716-69-1

Description

The occurrence of Paricalcitol Impurity 11 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Paricalcitol Impurity 11 (CAS 95716-69-1) is a high-purity analytical reference standard with the molecular formula C22H40O2Si and a molecular weight of 364.64 g/mol.

Based on its molecular formula C22H40O2Si, Paricalcitol Impurity 11 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 364.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
