INTRODUCTION
Pyruvic acid is a yellowish liquid with vinegar odor. Anatomically, it participates in biological synthesis and metabolic processes of carbohydrates, amino acids, and lipids. Its reactivity is attributed to the presence of two carbonyl groups adjacent to each other and thus the chemical is employed in many synthesis processes leading a variety of end-uses.
Manufacture
The acid is manufactured by ozonolysis of natural rubber (levulinic acid as by-product) or by DL-lactic acid oxidation or by distillation of tartaric acid over KHSO4.

L-Alpha glycerylphosphorylcholine (alpha-GPC or choline alfoscerate) is a choline-containing phospholipid. When ingested, alpha-GPC is metabolized into choline and glycerol-1-phosphate. Choline is a precursor of acetylcholine, a neurotransmitter involved in memory, attention, and skeletal muscle contraction.
3,3,3-Trifluoropropanol is a colorless liquid that is consumed in manufacture of value-added intermediates. This apart, the halogenated alcohol is also cited to have applications in other industry verticals. It also finds uses in proteomic research and in agrochemicals.
Calcium Gluconate is the calcium salt of gluconic acid, an oxidation product of glucose, and contains 9.3% calcium, which is about one-third of the calcium in the strength of calcium chloride. It is an ingredient found in a variety of supplements and vitamins and is used to lower potassium in the blood.
2-Amino-6-fluorobenzonitrile is a powder form chemical that has multiple uses ranging from medicine to intermediates to APIs. The structure of the compound depicts that it has an active fluorine atom in o-position to the nitrile group and this renders the molecule reactive. It thus participates in many synthetic processes.
Sodium Alginate is a linear polysaccharide derivative of alginic acid processed from brown algae. The conversion of alginic acid to sodium alginate allows its solubility in water, which assists its extraction. Sodium Alginate is used as a hydrocolloid in various applications such as food manufacturing and pharmaceuticals, as an emulsifier in textiles and cosmetics industries and in dentistry to make molds.
Chromium hydroxide, a gelatinous, polymeric inorganic powder, is amphoteric in nature. It reacts as an acid as well as a base. On heating, it decomposes to chromic oxide. The molecule is largely used in cosmetics and tanning industries.
Magnesium trisilicate is an inorganic compound that is used as a food additive. The additive is frequently used by fast food chains to absorb fatty acids and extract impurities formed while frying edible oils. It has good acid neutralizing properties.
1,3-Dihyrdoxyacetone is a hygroscopic, white powder with a minty odor. It is abundantly found in nature as derivative of starch and is an intermediate product of fructose metabolism. Acronymed as DHA, it is at large used in the cosmetic industry.
3-Chloroperoxybenzoic acid (MCPBA) is a peroxycarboxylic acid. A white solid, it is used widely as an oxidant in organic synthesis. MCPBA is often preferred to other peroxy acids because of its relative ease of handling.
