Guaiazulene impurity 11 CAS 24687-70-5

Description

The occurrence of Guaiazulene impurity 11 is closely related to a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Guaiazulene impurity 11 (CAS 24687-70-5) is a certified pharmaceutical impurity reference standard with the molecular formula C15H16O and a molecular weight of 212.29 g/mol.

The molecular framework of Guaiazulene impurity 11 (C15H16O) is characterized by a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Guaiazulene impurity 11 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.
