Chemical Structure

(3-Methylisoxazol-5-yl)methanol CAS 14716-89-3 chemical structure

Description

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

CATO supplies (3-Methylisoxazol-5-yl)methanol (CAS 14716-89-3), a certified reference material (molecular formula C5H7NO2, MW 113.11 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H7NO2, (3-Methylisoxazol-5-yl)methanol contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 113.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
