Chemical Structure

Doripenem Impurity 9(Sodium Salt) CAS Doripenem Impurity 20 (Sodium Salt) chemical structure

Description

The occurrence of Doripenem Impurity 9(Sodium Salt) is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Doripenem Impurity 9(Sodium Salt) (CAS Doripenem Impurity 20 (Sodium Salt), C10H16NO4SNa) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Doripenem Impurity 9(Sodium Salt) (C10H16NO4SNa) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Doripenem Impurity 9(Sodium Salt) 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.
