3-Aminoisoxazole-5-carbonitrile CAS 1368187-62-5 chemical structure

Description

CATO manufactures 3-Aminoisoxazole-5-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

3-Aminoisoxazole-5-carbonitrile (CAS 1368187-62-5) is a high-purity analytical reference standard with the molecular formula C4H3N3O and a molecular weight of 109.09 g/mol.

Structurally, 3-Aminoisoxazole-5-carbonitrile (C4H3N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 109.09 g/mol, it falls into the low-molecular-weight range. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
