Norepinephrine Impurity 42 CAS 28822-73-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Norepinephrine Impurity 42.

As a process- or degradation-related impurity, Norepinephrine Impurity 42 (CAS 28822-73-3, C8H10O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Norepinephrine Impurity 42 (C8H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

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 manufactures Norepinephrine Impurity 42 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.
