Chemical Structure

Ursodeoxycholic Impurity 15 CAS 6009-98-9 chemical structure

Description

The occurrence of Ursodeoxycholic Impurity 15 is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ursodeoxycholic Impurity 15 (CAS 6009-98-9) is a certified pharmaceutical impurity reference standard with the molecular formula C26H45NO6SNa and a molecular weight of 522.70 g/mol.

Structurally, Ursodeoxycholic Impurity 15 (C26H45NO6SNa) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 522.70 g/mol, it falls into the moderately-high-molecular-weight range. 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 Ursodeoxycholic Impurity 15 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.
