Budesonide EP Impurity B（Mixture of diastereomers） CAS 1040085-98-0

Description

The occurrence of Budesonide EP Impurity B（Mixture of diastereomers） is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Budesonide EP Impurity B（Mixture of diastereomers） (CAS 1040085-98-0) is a certified pharmaceutical impurity reference standard with the molecular formula C23H30O6 and a molecular weight of 402.48 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Budesonide EP Impurity B（Mixture of diastereomers） is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.48 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 Budesonide EP Impurity B（Mixture of diastereomers） 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.
