3-Ethoxyaniline CAS 621-33-0 chemical structure

Description

CATO manufactures 3-Ethoxyaniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

3-Ethoxyaniline (CAS 621-33-0), molecular formula C8H11NO and molecular weight 137.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H11NO, 3-Ethoxyaniline contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 137.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
