Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 282.30 g/mol gives Nevirapine N1-Oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Nevirapine N1-Oxide (CAS 162255-73-4), a certified reference material (molecular formula C15H14N4O2, MW 282.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Nevirapine N1-Oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Nevirapine N1-Oxide 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.
