Chemical Structure

Milrinone Impurity 34 CAS 7154-55-4 chemical structure

Description

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.

CATO supplies Milrinone Impurity 34 (CAS 7154-55-4), a pharmacopoeial impurity reference standard (molecular formula C6H8N2O2, MW 140.14 g/mol) used for the identification and quantification of trace impurities in APIs.

Milrinone Impurity 34 (C6H8N2O2) contains an amino-acid-derived structure, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Milrinone Impurity 34 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.
