Description
As a certified reference material (CRM), Gatifloxacin Related Compound D(3-Desmethyl Gatifloxacin) 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.
CATO supplies Gatifloxacin Related Compound D(3-Desmethyl Gatifloxacin) (CAS 112811-57-1), a certified reference material (molecular formula C18H20FN3O4, MW 361.37 g/mol) for analytical method development and quality control.
Gatifloxacin Related Compound D(3-Desmethyl Gatifloxacin) (C18H20FN3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
