organic material containing a carbonyl group and unsaturated nitrile/alkyne-like functionality
Sample & Measurement Parameters
Identification Result
0%The ordinary FTIR search does not support a firm compound-level identification for this sample. Although the nearest library entry is 5-phenyl-2-(prop-2-ynylamino)-1,3-oxazol-4-one, the library match quality is effectively absent and no direct or related literature evidence independently confirms that assignment. The measured spectrum is better treated as an organic material showing a strong carbonyl band near 1696 cm-1 together with absorptions in the 2136-2216 cm-1 region consistent with unsaturated triple-bond or nitrile-like functionality, plus multiple C-H stretching bands from an organic backbone
