2-Methylbutanoic acid, also known as 2-methylbutyric acid is a branched-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH(CH 3)CO 2 H, classified as a short-chain fatty acid. It exists in two enantiomeric forms, ( R )- and ( S )-2-methylbutanoic acid.
Nearly $3.6 billion Canadian (US $2.7 billion) worth of goods and services cross the border each day. About 60% of U.S. crude oil imports are from Canada, and 85% of U.S. electricity imports are ...
For esters such as ethyl acetate (CH 3 COOCH 2 CH 3), ethyl formate (HCOOCH 2 CH 3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The "-oate" changes to "-ate." Some simple examples, named both ways, are shown in the figure above.
The U.S. hospice industry has quadrupled in size since 2000. Nearly half of all Medicare patients who die now do so as a hospice patient — twice as many as in 2000, government data shows.
