Chemical Structure
Description
The occurrence of Ibandronate Monohydrate EP Impurity C is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ibandronate Monohydrate EP Impurity C (CAS 905808-25-5), a pharmacopoeial impurity reference standard (molecular formula C8H21NO7P2, MW 305.20 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, Ibandronate Monohydrate EP Impurity C is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Ibandronate Monohydrate EP Impurity C 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.
