3-Hydroxyazetidine Hydrochloride

3-Hydroxyazetidine Hydrochloride is useful intermediate in the synthesis of polypeptides.

4,6-Dihydroxypyrimidine

4,6-Dihydroxypyrimidine is used as intermediates of Azoxystrobin. It is also used for production of sulfa drugs, synthetic vitamin B4, and synthetic drugs such as anticancer and auxiliary.

Acacia gum

Calcium Titanate

Calcium titanate is a chemical compound. It can aid integration of bone implants, such as in hip replacement surgery. It has low dielectric loss, especially at microwave frequencies and is therefore used as dielectric material in ceramic capacitors.

Cellulose

Cellulose is an organic compound, a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked D-glucose units. For industrial use, cellulose is mainly obtained from wood pulp and cotton. It is mainly used to produce paperboard and paper, and used as binding agent,auxiliary agent in pharmaceutical products.Cellulose is the structural component of the primary cell wall of green plants, many forms of algae and the oomycetes,used in the laboratory as the stationary phase for thin layer chromatography.

Ethyl Cellulose

Ethyl Cellulose is a hydrophobic ethyl ether of cellulose, an inert, hydrophobic polymer and is essentially tasteless, odourless, colorless, non-caloric, and physiologically inert. Ethyl Cellulose is prepared from wood pulp or cotton by treatment with alkali and ethylation of the alkali cellulose with ethyl chloride. It is a derivative of cellulose in which some of the hydroxyl groups on the repeating glucose units are converted into ethyl ether groups. It has long been used as solvent-based tablet and pellet coating, tablet binder, to prepare microcapsules and microspheres, and both as film- and matrix- forming material for sustained-release dosage forms. It is mainly used as a thin-film coating material. It is also used as a food additive as an emulsifier, auxiliary material for pharmaceuticals. Ethylcellulose is used to mask an unpleasant taste or to improve the stability of a formulation. Ethylcellulose is directly extracted from plant fibre (cellulose, cotton) and is then chemically modified. Ethylcellulose is predominantly used in food supplements and flavourings in capsules. It functions as a binding and filling agent or serves as protective coating. Ethyl cellulose is a kind of cellulose ether, and it shows good thermo stability and electric properties. Its use is presently requested in the formulation of food supplements in dry applications e.g. as a controlled release agent and protective colloid and as a thickener/binder in hydrophobic matrices. Ethyl cellulose is used as a food additive as an emulsifier.

Hydroxypropyl Methylcellulose

Hydroxypropyl methylcellulose is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products. As a food additive, hydroxypropyl methylcellulose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin. It is used primarily in construction materials like tile adhesives and renders where it is used as a rheology modifier and water retention agent. Hydroxypropyl methylcellulose solutions were patented as a semisynthetic substitute for tear-film. In addition to its use in ophthalmic liquids, hydroxypropyl methylcellulose has been used as an excipient in oral tablet and capsule formulations, where, depending on the grade, it functions as controlled release agent to delay the release of a medicinal compound into the digestive tract. It is also used as a binder and as a component of tablet coatings. Other applications include paints, cosmetics and detergents.

Lysergic Acid

Lysergic Acid is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and some plants.It is usually produced by hydrolysis of lysergamides and also be synthesized in the laboratory by a complex total synthesis.Lysergic acid is a chiral compound with two stereocenters.Amides of lysergic acid, lysergamides, are widely used as pharmaceuticals and as psychedelic drugs (LSD).

Mephedrone

Mephedrone is a synthetic stimulant and entactogen drug of the amphetamine and cathinone classes.It is used as a very powerful painkiller (synthetic opiate) to treat heroin addicts. It is a legal substitute for heroin in treatment programs.Mephedrone is a recreational drug taken by users who want an amphetamine or ecstasy like effect.
