S-phrases are defined in Annex IV of European Union Directive 67/548/EEC: Safety advice concerning dangerous substances and preparations. The flash point of a flammable liquid is the lowest Temperature at which it can form an ignitable mixture in air In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly In Computer science, ACID ( Atomicity Consistency Isolation Durability) is a set of properties that guarantee that Database transactions are Solubility is the characteristic Physical property referring to the ability of a given substance the Solute, to dissolve in a Solvent. It has a melting point of 133°C and a boiling point of 300°C. The melting point of a solid is the temperature range at which it changes state from solid to Liquid. The boiling point of a liquid is the temperature at which the Vapor pressure of the liquid equals the environmental pressure surrounding the liquid
It is obtained from oil of cinnamon, or from balsams such as storax. Cinnamon ( Cinnamomum verum, synonym C zeylanicum) is a small Evergreen Tree 10–15 metres (32 Storax is also a name for trees in the genus Styrax Storax is the resinous exudate of the Sweetgum ( Liquidambar) occasionally It is also found in shea butter and is the best indication of its environmental history and post-extraction conditions. It can also be made synthetically.
Cinnamic acid is used in flavours, synthetic indigo, and certain pharmaceuticals, though its primary use is in the manufacturing of the methyl, ethyl, and benzyl esters for the perfume industry. A drug, broadly speaking is any chemical substance that when absorbed into the body Cinnamic acid has a "honey, floral odor" (Merck Index); it and its more volatile ethyl ester (ethyl cinnamate) are flavour components in the essential oil of cinnamon, in which related cinnamaldehyde is the major constituent. Esters are a class of Chemical compounds and Functional groups Esters consist of an inorganic or organic Acid in which at least Ethyl cinnamate is the Ester of Cinnamic acid and Ethanol. It is present in the essential oil of Cinnamon; pure ethyl cinnamate has a "fruity Cinnamon ( Cinnamomum verum, synonym C zeylanicum) is a small Evergreen Tree 10–15 metres (32 Cinnamic aldehyde or cinnamaldehyde (more precisely trans -cinnamaldehyde, the only naturally-occurring form is the Chemical compound that Cinnamic acid is also part of the biosynthetic shikimate and phenylpropanoid pathways. Shikimic acid, more commonly known as its anionic form shikimate, is an important biochemical Intermediate in plants and microorganisms Phenylpropanoids are a class of plant-derived Organic compounds that are biosynthesized from the Amino acid Phenylalanine. Its biosynthesis is performed by action of the enzyme phenylalanine ammonia-lyase (PAL) on phenylalanine. Biosynthesis is a phenomenon wherein Chemical compounds are produced from simpler Reagents Biosynthesis unlike Chemosynthesis, takes place within living Enzymes are Biomolecules that catalyze ( ie increase the rates of Chemical reactions Almost all enzymes are Proteins In Enzymology, a phenylalanine ammonia-lyase ( is an Enzyme that catalyzes the Chemical reaction L-phenylalanine \rightleftharpoons Phe redirects here For the BitTorrent feature see PHE.

Cinnamic acid is soluble in diethyl ether, insoluble in hexane. Diethyl ether, also known as ether and ethoxyethane, is a clear colorless and highly Flammable liquid with a low Boiling point and a Hexane is an Alkane Hydrocarbon with the Chemical formula CH3(CH24CH3 or C6H14
