Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 209.24 g/mol gives Ethyl 4-amino-3-ethoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 4-amino-3-ethoxybenzoate (CAS 342044-64-8), a certified reference material (molecular formula C11H15NO3, MW 209.24 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-amino-3-ethoxybenzoate (C11H15NO3) 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 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), Ethyl 4-amino-3-ethoxybenzoate 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.
