Organic Nitrogen Compounds. Amine, like butan-1-amine, and alcohol, like butan-1-ol. In the case of 1-(14)C-labelled butyrate, the appearance of radioactivity in the blood of injected mice is rapid and some of it is maintained for relatively long periods in different organs, mainly the liver. Join our newsletter! Introductory note on the infrared spectrum of butanoic acid. Notable peak: the strong band at 1712 cm-1 for the C=O. Formula: C 8 H 16 O 2; Molecular weight: 144.
