Quinoline in our webshop

Quinoline (1-azanaftalen, 1-benzazin, benzo-piridin) is an aromatic organic compound, and it has a heterocyclic structure.

The chemilcal formula of it is : C9H7N.
This colorless hydroscopic liquid  has a piercingly strong odor. Exposed to sunlight for a longer period of time,
it will turn yellow later brown.
It dissolves well in organic solvents, but not so well in cold water.
Quinoline is created in the processiong of paint and other metallurgical products.
It is mainly used in preservatives. It can also be used as a disinfectant or as a solvent and in the production of medicine, in yellow
medicines it is used as paint.
Quinoline is a toxic chemical, interferencing with human body it irritates the nostrils.
Long term effects are not known, but tests show, that it damages the liver.

Quinoline can be extracted from coal tar, and it can be found in oil shale.

It can be produced as follows:
1. With Doebner-Miller reaction using anilines and unsaturated carbonyl compounds
2. Friedländer synthesis using 2-aminobenzaldehyde and acetaldehyde.
3. Skraup synthesis using ferrous sulfate, glycerol, aniline, nitrobenzene, and sulfuric acid.
4. Povarov reaction using an aniline, a benzaldehyde and an activated alkene.

The melting point of quinoline is -15 °C and its densitiy is  1,09 g/ml.

Hydroxyquinoline in our webshop

A 8 – hydroxyquinoline heterocyclic quinoline derivative. Organic compound, with a placement of an OH-group on carbon number 8.

This light yellow compound is widely used commercially, although under a variety of names.
The complexes as well as the heterocycle itself exhibit antiseptic, disinfectant, and pesticide properties,
functioning as a transcription inhibitor.
Its solution in alcohol is used as liquid bandages.
It once was of interest as an anti-cancer drug.
The result of the reaction of 8 – hydroxyquinoline and aluminium is Alq3, which is a common component of organic light-emitting diodes.
The roots of the invasive plant Centaurea diffusa release 8-hydroxyquinoline, which has a negative effect on plants that have not co-evolved with it.
Hydroxyquinoline was used as a stabilizer of hydrogen peroxide.
