2-Bromobutyric acid is the organic compound with the molecular formula CH 3 CH 2 CH(Br)CO 2 H. It is a colorless liquid. The 2-position is stereogenic, so the compound is chiral. Optical resolution can be effected using strychnine. [1]
Crotonic acid adds hydrogen bromide to form 3-bromobutyric acid. [9] [10] The reaction with alkaline potassium permanganate solution affords 2,3-dihydroxybutyric acid. [9] Upon heating with acetic anhydride, crotonic acid converts to the acid anhydride: [11]
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...

8-Hydroxycarbostyril 1 is acylated with 2-bromobutyric acid chloride 2 at the fifth position of the quinoline system, which gives the compound 3. This undergoes action of isopropylamine, forming an aminoketone, the carbonyl group of which is reduced by sodium borohydride, giving procaterol 4 .
TBE or Tris/Borate/EDTA, is a buffer solution containing a mixture of Tris base, boric acid and EDTA.. In molecular biology, TBE and TAE buffers are often used in procedures involving nucleic acids, the most common being electrophoresis.
Butyric acid (/ ˈ b j uː t ɪ r ɪ k /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 COOH. It is an oily, colorless liquid with an unpleasant odor. Isobutyric acid (2-methylpropanoic acid) is an ...
For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: f eq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c(H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be called a "2 normal" solution.
