The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
It has the chemical formula (CH 3) 2 CHCH(CH 3) 2. It is a colorless liquid which boils at 57.9 °C. It is a colorless liquid which boils at 57.9 °C. References
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.
The alkyl (R') group is named first. The R−C(=O)O part is then named as a separate word based on the carboxylic acid name, with the ending changed from "-oic acid" to "-oate" or "-carboxylate" For example, CH 3 CH 2 CH 2 CH 2 COOCH 3 is methyl pentanoate, and (CH 3) 2 CHCH 2 CH 2 COOCH 2 CH 3 is ethyl 4-methylpentanoate.
2,2-Dimethylbutane, trivially known as neohexane at William Odling's 1876 suggestion, [4] is an organic compound with formula C 6 H 14 or (H 3 C-) 3-C-CH 2-CH 3. It is therefore an alkane , indeed the most compact and branched of the hexane isomers — the only one with a quaternary carbon and a butane (C 4 ) backbone.

An autopsy found MDMB-4en-PINACA and one of its metabolites (MDMB-4en-PINACA 3,3-dimethylbutanoic acid) in peripheral blood at a level of 0.4 μg/L and 5.7 μg/L and 0.5 μg/L and 11.6 μg/L in cardiac blood. Urine contained 2.1 μg/L for the metabolite, and a detection below level of quantification for MDMB-4en-PINACA itself. [23]
Dimethylbutadiene, formally referred to as 2,3-dimethyl-1,3-butadiene, is an organic compound with the formula (CH 3) 2 C 4 H 4. It is colorless liquid which served an important role in the early history of synthetic rubber. It is now a specialty reagent.
