Anol, also known as p-hydroxypropenylbenzene, [1] is a simple phenol that was derived via demethylation from anethole, an estrogenic constituent of anise and fennel, by Sir Charles Dodds in 1937. [ 2 ] [ 3 ] It was reported to possess extremely potent estrogenic activity on par with that of steroidal estrogens like estrone , with a dose of 1 ...
The noun steel originates from the Proto-Germanic adjective *stahliją or *stakhlijan 'made of steel', which is related to *stahlaz or *stahliją 'standing firm'. [4] The carbon content of steel is between 0.02% and 2.14% by weight for plain carbon steel (iron-carbon alloys). Too little carbon content leaves (pure) iron quite soft, ductile, and ...
2-Methyl-1-butanol (IUPAC name, also called active amyl alcohol) is an organic compound with the formula CH 3 CH 2 CH(CH 3)CH 2 OH. It is one of several isomers of amyl alcohol.This colorless liquid occurs naturally in trace amounts and has attracted some attention as a potential biofuel, exploiting its hydrophobic (gasoline-like) and branched structure.
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)
2-Methyl-2-pentanol (IUPAC name: 2-methylpentan-2-ol) is an organic chemical compound. It can be added to a gas chromatograph to help distinguish between branched compounds, especially alcohols. [2] Its presence in urine can be used to test for exposure to 2-methylpentane. [3]
R2 is a PM steel made by Kobe Steel Japan (Kobelco). It is also known as SG2 (Special Gold 2) when it is marked by Takefu Specialty Steel. SRS-15 is a High-Speed Tool Steel (HSS) where the 15 represents 1.5% C. One of the earliest known Japanese "super steels". The maker is unknown. A SRS-13 with 1.3% Carbon also exists.

2-Methyl-1-pentanol (IUPAC name: 2-methylpentan-1-ol) is an organic chemical compound. It is used as a solvent and an intermediate in the manufacture of other chemicals. [ 2 ] Due to its low solubility in water it has recently been suggested as a solvent in liquid–liquid extraction of ethanol from fermented feedstocks.
