6-Hydroxy-3-methylbenzoisoxazole CAS 66033-92-9

Description

Compared with other compounds in its class, the molecular weight of 149.15 g/mol gives 6-Hydroxy-3-methylbenzoisoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-Hydroxy-3-methylbenzoisoxazole (CAS 66033-92-9), a certified reference material (molecular formula C8H7NO2, MW 149.15 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6-Hydroxy-3-methylbenzoisoxazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
