Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Zoledronic Acid Impurity 2（Zoledronic Acid EP Impurity B）.
Zoledronic Acid Impurity 2（Zoledronic Acid EP Impurity B） (CAS 1627731-61-6) is a certified pharmaceutical impurity reference standard with the molecular formula C7H16N2O14P4 and a molecular weight of 476.10 g/mol.
The molecular framework of Zoledronic Acid Impurity 2（Zoledronic Acid EP Impurity B） (C7H16N2O14P4) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. 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.
CATO manufactures Zoledronic Acid Impurity 2（Zoledronic Acid EP Impurity B） under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
