Chemical Structure

Sodium Fusidate EP Impurity I CAS 5951-83-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium Fusidate EP Impurity I.

As a process- or degradation-related impurity, Sodium Fusidate EP Impurity I (CAS 5951-83-7, C29H46O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, a hydroxyl group, an ether linkage, Sodium Fusidate EP Impurity I is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 474.67 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 Sodium Fusidate EP Impurity I 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.
