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 Gadobutrol EP Impurity C (Gadoteridol USP Related Compound B).
Gadobutrol EP Impurity C (Gadoteridol USP Related Compound B) (CAS 112188-16-6) is a certified pharmaceutical impurity reference standard with the molecular formula C14H23N4O6Gd and a molecular weight of 500.61 g/mol.
Gadobutrol EP Impurity C (Gadoteridol USP Related Compound B) (C14H23N4O6Gd) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Gadobutrol EP Impurity C (Gadoteridol USP Related Compound 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.
