Zoledronic Acid EP Impurity B Chloride CAS 2043362-88-3

Description

The occurrence of Zoledronic Acid EP Impurity B Chloride is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Zoledronic Acid EP Impurity B Chloride (CAS 2043362-88-3) is a certified pharmaceutical impurity reference standard with the molecular formula C7H17N2O14P4Cl and a molecular weight of 512.56 g/mol.

The molecular framework of Zoledronic Acid EP Impurity B Chloride (C7H17N2O14P4Cl) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Zoledronic Acid EP Impurity B Chloride 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.
