General Description

(S)-2-fluoro-4-methylpentanoic acid is a chemical compound with the molecular formula C6H11FO2. It is a carboxylic acid with a fluorine atom and a methyl group attached to a pentanoic acid backbone. (S)-2-fluoro-4-methylpentanoic acid is chiral, meaning it has a non-superimposable mirror image, and the "S" in its name indicates its stereochemistry. (S)-2-fluoro-4-methylpentanoic acid is a building block in organic synthesis and can be used to create pharmaceuticals, agrochemicals, and other compounds. It has potential applications in the development of new drugs and materials due to its unique structure and reactivity. Additionally, its fluoro and methyl substituents can influence its properties and interactions with other molecules, making it a valuable tool in chemical research and development.

Check Digit Verification of cas no

The CAS Registry Mumber 126957-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,5 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126957-44:
(8*1)+(7*2)+(6*6)+(5*9)+(4*5)+(3*7)+(2*4)+(1*4)=156
156 % 10 = 6
So 126957-44-6 is a valid CAS Registry Number.

An unusual conformation of α-haloamides due to cooperative binding with zincated porphyrins

Tanasova, Marina,Yang, Qifei,Olmsted, Courtney C.,Vasileiou, Chrysoula,Li, Xiaoyong,Anyika, Mercy,Borhan, Babak

supporting information; experimental part, p. 4242 - 4253 (2011/02/25)

CD and NMR spectroscopic evidence of cooperative binding between an α-halogen atom and a carboxamide group with a zinc porphyrin leads to an unprecedented conformation for the determination of the absolute stereochemistry of α-haloamides (α-halocarboxylic acids derivatized with 1,4-phenylenediamine) through the use of exciton-coupled circular dichroism (ECCD). With the use of chiral lactams, whose rotomeric contributions are minimized, both ECCD and NMR spectroscopy demonstrate that the porphyrin favors binding to the side of the sterically more demanding halogen atom as compared to the smaller hydrogen atom. In all, the data is strongly suggestive of an unusual conformation not observed before for α-chiral amides. A mnemonic for determining the absolute stereochemistry of α-halogenated carboxylic acids is provided.

Synthesis and Ferroelectric Properties of 2,5-Diphenylpyrimidines with Different α-Fluorocarboxylic Acids

Boemelburg, Jan,Heppke, Gerd,Ranft, Andreas

, p. 1127 - 1131 (2007/10/02)

Chiral esters of 2--5-pyrimidine and 2--5-pyrimidine with four different α-fluorocarboxylic acids have been synthesized.The spontaneous polarization and the tilt angles in the smectic C* phase were measured as a function of temperature.All compounds exhibit wide range smectic C* phases, the highest values of the spontaneous polarization being about 400 nC/cm2.Additionally the spontaneous polarization in a higher ordered smectic phase was determined, the values ranging up to about 600 nC/cm2.The spontaneous polarization/tilt angle ratio strongly increases with decreasing temperature. - Keywords: Liquid Crystals, Smectic Liquid Crystals, Ferroelectric Properties, Chiral α-Fluorocarboxylic Acid Esters, 2,5-Diphenylpyrimidines
