3-(Thiophen-2-yl)isoxazole CAS 175205-65-9

Description

The occurrence of 3-(Thiophen-2-yl)isoxazole is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(Thiophen-2-yl)isoxazole (CAS 175205-65-9), a certified reference material (molecular formula C7H5NOS, MW 151.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H5NOS, 3-(Thiophen-2-yl)isoxazole contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 151.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
