3-chloro-2-methyl-butyric acid methyl ester is an organic compound with the chemical formula C6H11ClO2. It is a colorless liquid with a fruity odor and is derived from the esterification of 3-chloro-2-methyl-butyric acid with methanol. 3-chloro-2-methyl-butyric acid methyl ester is used as a flavoring agent in the food and beverage industry, particularly in the production of artificial fruit flavors. It is also employed as a fragrance ingredient in the cosmetics and perfumery sector. Due to its chemical structure, it exhibits properties such as solubility in organic solvents and limited solubility in water. The compound is synthesized through a series of chemical reactions, and its production is subject to strict quality control to ensure safety and efficacy in its applications.

815-75-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 815-75-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 815-75:
(5*8)+(4*1)+(3*5)+(2*7)+(1*5)=78
78 % 10 = 8
So 815-75-8 is a valid CAS Registry Number.

Free Radical Substitution. Part 38. The Effect of Solvent on the Atomic Chlorination and Bromination of 2-Substituted Butanes and the Importance of Steric Effects

Atto, Saeed Y.,Tedder, John M.,Walton, John C.

, p. 629 - 634 (2007/10/02)

The relative selectivity of atomic halogenation of 2-substituted butanes is influenced by the phase and by solvents.There are solvents which increase the selectivity compared with the gas phase and solvents which decrease the relative selectivity.However the most striking feature of the halogenation (especially the bromination) of 2-substituted butanes is the high reactivity of the 2-position notwithstanding very unfavourable polar effects.This reactivity is attributed to the release of steric compression associated with the abstraction of the tertiary hydrogen atom.The halogenation of butan-2-ol esters is associated with some decomposition of 2-butyl radical (OCOR)CH3> and the chlorination of 2-phenylbutane with the formation of olefins 2-phenylbut -1-ene and 2-phenylbut-2-ene.

Chlorination of Carboxylic Acid Derivatives. VIII. Liquid Phase Chlorination of the Aliphatic C5-Carboxylic Acids and Their Chlorides, Methyl Esters and Chloromethyl Esters with Chlorine

Kornonen, Ilpo O. O.

, p. 467 - 474 (2007/10/02)

The chlorination of pentanoic, 3-methylbutanoic, 2-methylbutanoic and 2,2-dimethylpropanoic acids and their derivatives with chlorine in the liquid phase have been investigated.The monochloro products formed were determined by gas-liquid chromatography (GLC) and gas-liquid chromatography-mass spectrometry (GLC-MS) as their esters through the comparison with authentic samples.The deactivation of position 2 decreases in the order COCl > CO2H > CO2CH2Cl > CO2CH3, the effect of the COCl-group in pentanoic acid derivatives being 4.3 times stronger than that of the CO2CH3-group.The deactivation is smallest in 2-methylbutanoic acid derivatives owing to the electron-donating methyl group.The EI mass spectra of the methyl and chloromethyl esters have been studied in detail.
