Ciclesonide Impurity 3 CAS 204444-44-0 chemical structure

Description

CATO manufactures Ciclesonide Impurity 3 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.

As a process- or degradation-related impurity, Ciclesonide Impurity 3 (CAS 204444-44-0, C28H38O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Ciclesonide Impurity 3 (C28H38O6) contains a steroid core, a hydroxyl group, an ether linkage. 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
