Chemical Structure

Gadobutrol Impurity 113 CAS 77-76-9 chemical structure

Description

As a certified reference material (CRM), Gadobutrol Impurity 113 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.

CATO supplies Gadobutrol Impurity 113 (CAS 77-76-9), a pharmacopoeial impurity reference standard (molecular formula C5H12O2, MW 104.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C5H12O2, Gadobutrol Impurity 113 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 104.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
