Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 127.14 g/mol gives (5-Ethylisoxazol-4-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (5-Ethylisoxazol-4-yl)methanol (CAS 155602-38-3), a certified reference material (molecular formula C6H9NO2, MW 127.14 g/mol) for analytical method development and quality control.
(5-Ethylisoxazol-4-yl)methanol (C6H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
