Oxygen is a chemical element with the symbol O and the atomic number of 8. It is a member of the chalcogen on the periodic table and a highly active non-metallic element. Oxygen can be used for cellular respiration. The major classes of organic molecules in the organism contain oxygen, such as proteins, nucleic acids, carbohydrates and fats, as well as inorganic compounds, the major component of animal skins, teeth and bones.
Alfa Chemistry can offer a range of competitive oxygen compounds.
Applications
Industry: Alcohol is organic compound with a hydroxyl functional group (-OH) bound to a saturated carbon atom. Some alcohols, mainly ethanol and methanol, can be used as fuel. After the turbocharger or supercharger has pressurized the air, the performance of the fuel in the forced-induction internal combustion engine can be increased by injecting the alcohol into the intake port. This cools the pressurized air, providing a denser air charge, which allows more fuel and therefore more power. Pentanol is used as a solvent for coating CDs and DVDs and it has all the properties necessary to replace gasoline as an internal combustion fuel.
Medical chemistry: Isoetarine is a selective short-acting β2 adrenergic receptor agonist. In the β2 agonist family, it is called "granddaughter of adrenalin" and can rapidly relieve bronchospasm and asthma. Epinephrine is the first, followed by isoproterenol. Isoetharine is the third drug in this line, the third generation of the original. Ethanol is used as an antiseptic to disinfect the skin before injecting, usually with iodine. Alcohol-based soap is commonly used in restaurants and is convenient for there is no need to dry the soap because of the volatility of the alcohol. Alcohol-based gel has become common as hand lotion.
Organic chemistry: An orthoester is a functional group containing three alkoxy groups attached to one carbon atom. Orthoesters are usually considered as products of exhaustive alkylation of unstable orthocarboxylic acids. An typical example is ethyl orthoacetate, more correctly known as 1,1,1-triethoxyethane. Orthoesters are used in organic synthesis as protecting groups for esters. Both triethylorthoacetate and trimethylorthoacetate are commonly used reagents with protecting groups in organic chemistry. Another example is the OBO protecting group (4-methyl-2,6,7-trioxa-bicyclo[2.2.2]octan-1-yl) which was developed by Elias James Corey and is formed by the action of (3-methyloxetan-3-yl)methanol on activated carboxylic acids in the presence of Lewis acids. The group is base stable and can be cleaved within two steps under mild conditions, mildly acidic hydrolysis yields the ester of tris(hydroxymethyl)ethane which is then cleaved using an aqueous carbonate solution.
