Chemical Structure
Description
The occurrence of Ceftolozane Impurity 14 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ceftolozane Impurity 14 (CAS CATO-C4X-240614), a pharmacopoeial impurity reference standard (molecular formula C11H15N3O3, MW 237.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ceftolozane Impurity 14 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Ceftolozane Impurity 14 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.
