Chemical Structure

Budesonide Impurity N20 CAS 3754-05-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 374.43 g/mol gives Budesonide Impurity N20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Budesonide Impurity N20 (CAS 3754-05-0, C21H26O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Budesonide Impurity N20 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.43 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).

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.

CATO manufactures Budesonide Impurity N20 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.
