Chemical Structure
Description
The occurrence of 3-Cyclopropyl-2-nitroaniline is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Cyclopropyl-2-nitroaniline (CAS 2097553-56-3) is a high-purity analytical reference standard with the molecular formula C9H10N2O2 and a molecular weight of 178.19 g/mol.
The molecular framework of 3-Cyclopropyl-2-nitroaniline (C9H10N2O2) is characterized by an amino-acid-derived structure, 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. 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), 3-Cyclopropyl-2-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.
