《Development of carboxylic acid search prefilters for spectral library matching》 was published in Microchemical Journal in 2012. These research results belong to Lavine, Barry K.; Nuguru, Kadambari; Mirjankar, Nikhil; Workman, Jerome. Quality Control of 2-Hydroxy-N-phenylacetamide The article mentions the following:
435 IR absorbance spectra of 140 carboxylic acids and 295 noncarboxylic acids which included aldehydes, ketones, esters, amides as well as compounds containing both carbonyls and alcs. were preprocessed using the wavelet packet tree to enhance subtle but important features in the data. Wavelet coefficients that optimized the separation of the spectra by functional group in a plot of the two largest principal components of the data were identified using a genetic algorithm (GA) for pattern recognition anal. Because principal components maximize variance, the bulk of the information encoded by the wavelet coefficients selected by the pattern recognition GA is characteristic of the carboxylic acid functional group. The carboxylic acid search prefilter developed as part of this study was successfully validated using two external validation sets. The 1st validation set consisted of 24 carboxylic acids and 61 noncarboxylic acids and the 2nd validation set consisted of 264 carboxylic acids and 72 noncarboxylic acids. In the part of experimental materials, we found many familiar compounds, such as 2-Hydroxy-N-phenylacetamide(cas: 4746-61-6Quality Control of 2-Hydroxy-N-phenylacetamide)
2-Hydroxy-N-phenylacetamide(cas: 4746-61-6) belongs to amides.Quality Control of 2-Hydroxy-N-phenylacetamideAmides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
