Discontinued product1-Bromo-4-cyclopentylbenzene
CAS:1-Bromo-4-cyclopentylbenzene (1-BCPB) is a chlorinated aromatic compound that can be synthesized by reacting 1-bromo-4-chlorobenzene and cyclopentylmagnesium bromide. The reaction sequence begins with the addition of hydrochloric acid to the first reactant, followed by magnesium chloride and ether. The mixture is heated to produce a liquid solution of ethylhexyloxy pyridine, which reacts with the second reactant in a sequence that leads to the desired product. 1-BCPB is used as an intermediate in organic synthesis. It has been shown to have moderate interaction with paraldehyde and pyridinium salts at room temperature, but it does not react with cycloalkyls or pyridinium salts at elevated temperatures.

CAS:The synthesis of 2-methyl-3-oxo-pentanoic acid methyl ester is accomplished by a three step process. The first step is the intramolecular condensation of 2,2-dimethylpropionic acid with acetone to form a 1:1 mixture of 3,4-dihydroxybutyl and 4,4-dihydroxybutyl esters. The second step is the selective transesterification of the 3,4-dihydroxybutyl ester with benzaldehyde. This reaction provides an optically pure 2-methyl-3-oxo-pentanoic acid methyl ester as the major product. The third step is an aldol condensation between the ketone from the second step and acetone to produce another optically pure 2,2 dimethylpropionic acid methyl ester.Formula:C7H12O3Purity:Min. 95%Molecular weight:144.17 g/mol4-Bromo-1-N-cyclopropylbenzene-1,2-diamine
