Description

Compared with other compounds in its class, the molecular weight of 245.10 g/mol gives 5-(5-Bromothiophen-2-yl)isoxazol-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(5-Bromothiophen-2-yl)isoxazol-3-amine (CAS 1267246-49-0), molecular formula C7H5BrN2OS and molecular weight 245.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(5-Bromothiophen-2-yl)isoxazol-3-amine (C7H5BrN2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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