Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 226.23 g/mol gives N-Benzylidene-4-nitroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Benzylidene-4-nitroaniline (CAS 785-81-9) is a high-purity analytical reference standard with the molecular formula C13H10N2O2 and a molecular weight of 226.23 g/mol.
The molecular framework of N-Benzylidene-4-nitroaniline (C13H10N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), N-Benzylidene-4-nitroaniline 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.
