Chemical Structure

4-Ethylisoxazol-5-amine CAS 1249965-64-7 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, 4-Ethylisoxazol-5-amine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

4-Ethylisoxazol-5-amine (CAS 1249965-64-7) is a high-purity analytical reference standard with the molecular formula C5H8N2O and a molecular weight of 112.13 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 4-Ethylisoxazol-5-amine 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.
