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 Impurity 153.
CATO supplies Gadobutrol Impurity 153 (CAS CATO-C4X-2120153), a pharmacopoeial impurity reference standard (molecular formula C20H44N4O9HCl, MW 521.05 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Gadobutrol Impurity 153 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 521.05 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
