What is the Methyl Butyrate?

The molecule Methyl Butyrate presents a molecular formula of C5H10O2 and its IUPAC name is methyl butyrate.

Methyl butyrate (also known as butanoic acid methyl ester) is a clear, colorless liquid with a fruity odor. It is insoluble in water but soluble in most organic solvents. Methyl butyrate is produced naturally in some fruits and vegetables, and is also found in butter and cheese. It can be synthesized from butyric acid and methanol..

Methyl butyrate is used as a flavoring agent in food and beverages, and as a fragrance in cosmetics and personal care products. It is also used as a solvent and plasticizer..

Methyl butyrate is a flammable liquid and should be stored in a cool, dry place..

Other names (synonyms)

IUPAC nomenclature provides a standardized method for naming chemical compounds. Although this system is widely used in chemistry, many chemical compounds have also other names commonly used in different contexts. These synonyms can come from a variety of sources and are used for a variety of purposes.

One common source of synonyms for chemical compounds is the common or trivial names, assigned on the basis of appearance, properties, or origin of the molecule.

Another source of synonyms are historical or obsolete names employed in the past, however replaced nowadays by more modern or standardized names.

In addition to common and historical names, chemical compounds may also have synonyms that are specific to a particular field or industry.

LogP and topological polar surface area (TPSA) values were estimated using Open Babel software.

The n-octanol/water partition coeficient (Kow) data is applied in toxicology and drug research. Kow values are used, to guess the environmental fate of persistent organic pollutants. High partition coefficients values, tend to accumulate in the fatty tissue of organisms. Molecules with a log(Kow) (or LogP) greater than 5 are considered to bioaccumulate.

TPSA values are the sum of the surface area over all polar atoms or molecules, mainly oxygen and nitrogen, also including hydrogen atoms.

In medicinal chemistry, TPSA is used to assess the ability of a drug to permeabilise cells.

For molecules to penetrate the blood-brain barrier (and act on receptors in the central nervous system), TPSA values below 90 Å2 are required. Thus, molecules with a polar surface area greater than 140 Å2 tend to be poorly permeable to cell membranes.
