Chemical Structure

4-Ethyl-3-methylisoxazol-5-amine CAS 91084-67-2 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, 4-Ethyl-3-methylisoxazol-5-amine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 4-Ethyl-3-methylisoxazol-5-amine (CAS 91084-67-2), a certified reference material (molecular formula C6H10N2O, MW 126.16 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
