In organic chemistry a functional group is used to describe the structures in a molecule. Functional groups are defined as a group of atoms that are bonded together. Functional groups are considered an important part of the molecule because the functional groups will determine how that molecule rea...
Esters are chemical compounds derived from an acid where at least one -OH (hydroxyl) group is replaced by an -O- (alkoxy) group, while ethers are a class of organic compounds that contain an oxygen atom connected to two alkyl or aryl groups.
NBS is a chemical reagent used in organic chemistry in electrophilic addition reactions and radical substitution. In bromination of olefins; in oxidation of alcohols to aldehydes and ketones and of aldehydes to acid bromides. N-Bromosuccinimide (NBS) in combination with LiBr can also be used in ...
The adjacent bis-THF subunit was constructed by a multiple Williamson reaction. The left and the right side chain were added by addition of organomagnesium compounds to aldehyde functions. The conversion of a carboxylic acid into the butenolide moiety concluded both syntheses. Zhou et al. reported...
Due to the influence of the chlorine atom, its alkalinity is slightly weaker than that of aniline. This substance can be used as an intermediate in organic synthesis and medicinal chemistry, and it is widely used in the structural modification and production of drug and pesticide molecules in fi...
Cyclopropylacetic acid, also known as Cyclopropylacetic acid, is a colorless liquid that can dissolve in most common organic solvents. It is a modified cyclopropane and serves as an intermediate in organic synthesis and the production of medical anesthetics.Synthesis Method Figure 1: Synthesis route ...

Silicone Chemistry Overview Silicone or polydimethylsiloxane (PDMS) is an inorganic polymer derived from silica (sand). It consists of a silicone backbone chain with organic methyl groups attached to the silicon atoms: The Si-O bond gives high temperature stability, while the methyl groups (CH3) ...
As for personal care products, only Disodium EDTA is detected in wastewater, while in groundwater the concentrations of all the analyzed substances are lower than the instrumental detection limit. Keywords: sewer; leakage; urban semi-confined groundwater; personal care products; microbiological ...
