Chemical Structure

Gadobutrol Impurity 17 CAS 127723-03-9 chemical structure

Description

Owing to an organic framework, Gadobutrol Impurity 17 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.27 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.

CATO supplies Gadobutrol Impurity 17 (CAS 127723-03-9), a pharmacopoeial impurity reference standard (molecular formula C8H20N4, MW 172.27 g/mol) used for the identification and quantification of trace impurities in APIs.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Gadobutrol Impurity 17 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.
