Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(2-methoxyphenyl)-2,4-dinitroaniline (CAS 14038-08-5), molecular formula C13H11N3O5 and molecular weight 289.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2-methoxyphenyl)-2,4-dinitroaniline (C13H11N3O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), N-(2-methoxyphenyl)-2,4-dinitroaniline 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.
