    The IR spectra of aspartic acid, phenylalanine and aspartyl-phenylalanine methyl ester, all show a significant absorption band centred around cm The solubility of magnesium oxide in water at 25C is only 0. The accuracy of this analysis in determining the percentage purity of the sample depends on the assumption that the only substance that reacts with hydrochloric acid was magnesium oxide.
