Chemical Structure

Paricalcitol Impurity 26 CAS CATO-C4X-138726 chemical structure

Description

The occurrence of Paricalcitol Impurity 26 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Paricalcitol Impurity 26 (CAS CATO-C4X-138726) is a certified pharmaceutical impurity reference standard with the molecular formula C19H32O and a molecular weight of 276.46 g/mol.

Based on its molecular formula C19H32O, Paricalcitol Impurity 26 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.46 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Paricalcitol Impurity 26 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
