Chemical Structure

3-methyl-4,5-dihydro-5-isoxazolecarboxylic acid 774-67-4 CAS 774-67-4 chemical structure

Description

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.

CATO supplies 3-methyl-4,5-dihydro-5-isoxazolecarboxylic acid 774-67-4 (CAS 774-67-4), a certified reference material (molecular formula C10H20N2O, MW 184.28 g/mol) for analytical method development and quality control.

The molecular framework of 3-methyl-4,5-dihydro-5-isoxazolecarboxylic acid 774-67-4 (C10H20N2O) is characterized by 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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