5,6,7,8-Tetrahydronaphthalene-1-carboxylic acid
In the mol-ecule of the title compound, C(11)H(12)O(2), the cyclo-hexane ring adopts a half-chair conformation. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by pairs of O-H⋯O hydrogen bonds, and the dimers are linked together by π-π inter-actions [centroid-centroid distance = 3.8310 (13) Å] and C-H⋯O bonds.
متن کامل1-Methyl-1H-indazole-3-carboxylic acid
The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.

[ ZH2 IACC) ; 1-amino [ 2R, 3E-2H2] cyc lopropaneIcar boxy 1 ic acid (trans-[zH2]ACC) : and l-amino[2,2.3.3-~H~]cyclopropane1-carboxylic acid are described. The [2,2-2H2]and [2,2,3.3-2H4]ACC compounds were prepared from the appropriately deuterated 2-bromoethanol 4-methylbenzenesulfonates by reaction with ethyl isocyanoacetate and two moles oE sodium hydride. The transr2H2]ACC and &[2H2]ACC wer...
متن کاملCarboxylic Acid Production
Carboxylic acids are central compounds in cellular metabolism, and in the carbon cycle in nature. Carbon dioxide is captured from the atmosphere and enters living cells through the formation of carboxylic groups, and it is released from living cells by the decarboxylation of carboxylic acids. The aerobic extraction of free energy from sugars in cellular respiration hinges on the ingeniously des...
متن کامل5-Amino-1-phenyl-1H-pyrazole-4-carboxylic acid
In the mol-ecule of the title compound, C(10)H(9)N(3)O(2), the pyrazole ring is approximately coplanar with the amino and carboxyl groups. The phenyl group is twisted by 48.13 (3)° relative to this plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation of the mol-ecule. The mol-ecules are linked into two-dimensional sheets by two strong inter-molecular N-H⋯N and O-H⋯O ...
