Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 487.50 g/mol gives Nemonoxacin Impurity 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Nemonoxacin Impurity 1 (CAS 2770004-80-1), a pharmacopoeial impurity reference standard (molecular formula C24H29N3O8, MW 487.50 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Nemonoxacin Impurity 1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 487.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Nemonoxacin Impurity 1 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.
