Chemical Structure
Description
CATO manufactures Ibandronate Impurity 20 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.
CATO supplies Ibandronate Impurity 20 (CAS 2271411-87-9 (free base)), a pharmacopoeial impurity reference standard (molecular formula C9H23NO8P2HCl, MW 371.69 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, chlorine substitution, Ibandronate Impurity 20 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
