Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.20 g/mol gives 2-Np-Aoz distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Np-Aoz (CAS 19687-73-1), a certified reference material (molecular formula C10H9N3O4, MW 235.20 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Np-Aoz is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.20 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Np-Aoz 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.
