Chemical Structure

Pasireotide Impurity 19 CAS CATO-C4X-200819 chemical structure

Description

The occurrence of Pasireotide Impurity 19 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pasireotide Impurity 19 (CAS CATO-C4X-200819) is a certified pharmaceutical impurity reference standard with the molecular formula C55H60N8O8 and a molecular weight of 961.11 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Pasireotide Impurity 19 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 961.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Pasireotide Impurity 19 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.
