- Bisphenol A (BPA) is an organic synthetic compound with the chemical formula (CH 3) 2 C(C 6 H 4 OH) 2 belonging to the group of diphenylmethane derivatives and bisphenols, with two hydroxyphenyl groups.It is a colorless solid that is soluble in organic solvents, but poorly soluble in water.isphenol A is used primarily to make plastics, and products using bisphenol A-based plastics have been in commercial use since 1957. At least 3.6 million tonnes (8 billion pounds) of BPA are used by manufacturers yearly.

- Isoprenaline (INN) or isoproterenol (USAN, trade names Medihaler-Iso and Isuprel) is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma.In humans, it is a non-selective beta-adrenergic agonist and TAAR1 agonist that is structurally similar to adrenaline.ses [edit]. Its primary use is for bradycardia or heart block. By activating β 1 -receptors on the heart, it induces positive chronotropic, dromotropic, and inotropic effects. It can be used as an inhaled aerosol to treat asthma, although this is currently a rare treatment.

Xenon - Xe Xenon. Xenon is a rare, odorless, colourless, tasteless, chamically unreactive gas. It was regarded as completely inert until, in 1962, Neil Barlett reported synthesis of xenon haxafluoroplatinate. In a gas filled tube xenon emits blue light when excited by electrical discharge. Applications. Xenon has relatively little commercial use.

The Disease-Fighting Power of Polyphenols Polyphenol: A kind of chemical that (at least in theory) may protect against some common health problems and possibly certain effects of aging.Polyphenols act as antioxidants. They protect cells and body chemicals against damage caused by free radicals, reactive atoms that contribute to tissue damage in the body.For example, when low-density lipoprotein (LDL) cholesterol is oxidized, it can become glued to arteries and cause coronary heart disease.olyphenols act as antioxidants.

Phenol Uses of phenol. The most important chemical made from phenol is bisphenol A, which is used to make the polycarbonates. Phenol is also catalytically reduced to cyclohexanol, which is used in the manufacture of polyamides 6 and 6,6.Phenol is also used to make a range of thermosetting polymers (resins).henol. The production of phenol from benzene is the first step in the manufacture of some very important polymers, including polyamides (nylons), polycarbonates and the phenolic resins.

Bisphenol A Bisphenol A is an endocrine disruptor that can mimic estrogen and has been shown to cause negative health effects in animal studies. To be specific, bisphenol A closely mimics the structure and function of the hormone estradiol with the ability to bind to and activate the same estrogen receptor as the natural hormone.PA is employed to make certain plastics and epoxy resins. BPA-based plastic is clear and tough, and is made into a variety of common consumer goods, such as water bottles, sports equipment, CDs, and DVDs.

Phenols and Salicylates: What They Are and Why It Matters Phenols are nothing more than natural chemicals made up of a benzene ring with one or more hydroxyl (OH) groups attached to it (science talk for how it is put together).n a normal body, one with the correct levels of sulfates and liver enzymes, phenols and salicylates are easily metabolized. The body utilizes what it needs from the chemicals and properly disposes of the rest through the bowels.
