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.

Applications
Pyruvic acid has medicinal properties and is reported to improve cardiac function. Food Grade is suitable for consumption by vegetarians and lacto-vegetarians.
Further, it is also an aroma chemical for its sharp sour acetic caramellic odor.
Synthetically, it is employed to make pharmaceuticals, agrochemicals, amino acids and intermediates. Some of the intermediates made from the acid find usage in sedatives and antioxidants.

Sodium trifluoroacetate is a colorless organic solid belonging to category of fluoro compounds. It acts as a versatile trifluoromethylation agent in chemicals synthesis and is used to produce an array of chemical intermediates.
Iodopropynyl butylcarbamate, also known as IPBC, is an antimicrobial ingredient commonly used in cosmetics. It appears as a white, crystalline powder. It is not a paraben; it belongs to a different chemical class called carbamates. It is soluble in both water and oil-based systems. IPBC was invented in the 1970s and has a long history of effective use as an antifungal technology.
Stevia extract with Rebaudioside A (98%) is one of the sweet tasting steviol glycoside, extracted and purified from Stevia rebaudiana (Bertoni) – a small perennial shrub also known as “Honey leaf”. The leaves of S. rebaudiana contain more than 30 different steviol glycosides, among which stevioside and rebaudioside A are present in the highest levels. It is non-nutritive and tastes approximately 200-300 times sweeter than sucrose.
Protoporphyrin IX dimethyl ester, abbreviated PPMX, is an organic moiety belonging to category porphyrins. On exposure to light, PPMX releases reactive oxygen that can be used to destroy targeted cancer cells and thus it find applications largely in medicines.
Cetylpyridinium chloride is the chloride salt form of cetylpyridinium, a quaternary ammonium with broad-spectrum antimicrobial activity. Upon topical administration, cetylpyridinium chloride is positively charged and reacts with the negatively charged microbial cell surfaces, thereby destroying the integrity of the cell membrane.
N2-Isobutyryl-2′-O-methyl-guanosine (IBG) is a modified nucleoside that has gained significant attention in recent years due to its potential therapeutic and industrial applications. IBG is a derivative of guanosine, a nucleoside that is a building block of RNA and DNA.
Trimethylaluminium belongs to class of organometallics. It is a highly reactive chemical and its solution in toluene is normally used to facilitate workability. Its general applications are in cross coupling and carboalumination reactions.
Octenidine dihydrochloride is a cationic surfactant, with a gemini-surfactant structure. Since 1987, it has been used primarily in Europe as an antiseptic prior to medical procedures, including on neonates. It is safe to handle and chemically stable.
Allyl Glycidyl Ether (AGE) is a multifunctional organic intermediate made from epichlorohydrin and allyl chloride and is featured by high functionality and low chlorine content. Since it has an epoxy group and an allyl group, AGE reacts with a wide range of compounds.
