Usage

Description

METHYL 9,10-DIBROMOSTEARATE is a chemical compound derived from stearic acid, a saturated fatty acid found in animal and vegetable fats. It is a colorless to pale yellow liquid that is insoluble in water but soluble in organic solvents. METHYL 9,10-DIBROMOSTEARATE is used as an intermediate in the synthesis of various organic compounds and can also function as a lubricant and a surfactant. Due to its potential for skin and eye irritation, as well as harmful effects if ingested or inhaled, it is crucial to handle METHYL 9,10-DIBROMOSTEARATE with care and store it in a cool, dry place away from ignition sources.

Products of the determination of the iodine value with iodine monobromide

The iodine value (iodine number) is an important analytical characteristic of fats and oils. Leading pharmacopeias determine it using iodine monobromide (Hanus method). We used methyl oleate as a simple analog of unsaturated triacylglycerols to identify the products. After performing the reaction in deuterated solvents under pharmacopeial conditions, NMR spectroscopy revealed the presence of the 9, 10-diiodo, 9, 10-dibromo, and 9, 10-bromoiodo adducts, leaving no educt olefin. The prescribed subsequent addition of potassium iodide led to the formation of methyl 9, 10diiodo and bromoiodo stearate in equal amounts.

Ultrasound in fatty acid chemistry: facile dehydrobromination of dibromo fatty esters to acetylenic ester derivatives

Dehydrobromination of dibromo derivatives of olefinic fatty acids was accomplished using KOH in 20percent aqueous ethanol under cocomitant ultrasonic irradiation (20 kHz) for 30 min at ambient temperature to give the corresponding acetylenic fatty acid derivatives (52-72percent yield).Ten different dibromo fatty acid substrates were used.Products include: fatty acids with a terminal or internal acetylenic bond; acetylenic fatty acids containing an additional functional group, such as hydroxy, chloro or azide group.The structures of the products were characterized by infrared and NMR spectroscopy. - Keywords: acetylenic fatty esters; dehydrobromination; dibromo fatty esters; ultrasond

Fatty Tetrazoles from Long Chain Olefinic Substrates

Methyl undec-10-enoate (I), oct-1-ene (II) and methyl octadec-9(Z)-enoate (VII) have been converted into α-bromoalkyltetrazole derivatives (V, IX) using bromine, nitriles and sodium azide as reagents.Dehydrobromination of the α-bromoalkyltetrazoles with sodium ethoxide furnishes the alkenyltetrazoles (VI, X).
