Chemical Structure

Ceftazidime dimer 2 CAS CATO-C4X-121265 chemical structure

Description

The occurrence of Ceftazidime dimer 2 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ceftazidime dimer 2 (CAS CATO-C4X-121265), molecular formula C43H45N11O17S4 and molecular weight 1116.14 g/mol, is a CATO reference standard with documented purity and traceability.

Ceftazidime dimer 2 (C43H45N11O17S4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ceftazidime dimer 2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
