  2. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. The di-, tri- etc. prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane).

  3. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

  4. 3-Methylhexane - Wikipedia

    en.wikipedia.org/wiki/3-Methylhexane

    3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane. The molecule is chiral, and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane. The enantiomers are (R)-3-methylhexane [3] and (S)-3-methylhexane. [4]

    Ethylvanillin can be methylate to 4-ethoxy-3-methoxybenzladehyde. The 4-ethoxy-3-methoxybenzaldehyde is then subjected to a Bayer-Villiger oxidation with peracetic acid and acetic acid to yield 4-ethoxy-3-methoxyphenol. The 4-ethoxy-3-methoxyphenol is methylated to yield 2,4-dimethoxy-1-ethoxybenzene. The 2,4-dimethoxy-1-ethoxybenzene is ...

    C 6 H 12 O 6 → 3 CH 4 + 3 CO 2. These hydrocarbon deposits, collected in porous rocks trapped beneath impermeable cap rocks, comprise commercial oil fields. They have formed over millions of years and once exhausted cannot be readily replaced. The depletion of these hydrocarbons reserves is the basis for what is known as the energy crisis.

  8. Ethoxylation - Wikipedia

    en.wikipedia.org/wiki/Ethoxylation

    In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C 2 H 4 O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R(OC 2 H 4) n OH, where n ranges from 1 to 10. Such compounds ...

    3-Methoxy-4-ethoxyphenethylamine (MEPEA) is a lesser-known psychedelic drug. It was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the minimum dosage is listed as 300 mg, and the duration unknown. [1] MEPEA is said to produce a light lifting feeling and a +1 on the Shulgin Rating Scale. Very ...
