1,2-Butanediol is a byproduct of the production of 1,4-butanediol from butadiene. [8] It is also a byproduct of the catalytic hydrocracking of starches and sugars such as sorbitol to ethylene glycol and propylene glycol. [9] It can also be obtained from the dihydroxylation of but-1-ene by OsO 4.
2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol; and one unstable geminal diol: 2-methylpropane-1,1-diol (not a glycol), hydrate of 2-methylpropanal (isobutyraldehyde) These three methylpropanediols are structural isomers of butanediols. They are not chiral.
[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
1,4-Butanediol, also called Butane-1,4-diol (other names include 1,4-B, BD, BDO and 1,4-BD), [5] is a primary alcohol and an organic compound with the formula HOCH 2 CH 2 CH 2 CH 2 OH. . It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glyco
1,4-Butynediol is a precursor to 1,4-butanediol and 2-butene-1,4-diol by hydrogenation. It is also used in the manufacture of certain herbicides, textile additives, corrosion inhibitors, plasticizers, synthetic resins, and polyurethanes. It is the major raw material used in the synthesis of vitamin B 6. [5]
1,3-Butanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 OH. With two alcohol functional groups, the molecule is classified as a diol . The compound is also chiral, but most studies do not distinguish the enantiomers.
The reasoning so far is simple: Just as a GLP-1 can make eating food less enjoyable because it modulates your brain’s pleasure and reward center, doctors say that it could impact how you feel ...
[1] 1,4-BD is a known prodrug of GHB which is converted into it through the actions of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). [ 5 ] [ 6 ] γ-Hydroxybutyraldehyde (GHBAL) is an intermediate in this pathway, [ 5 ] [ 6 ] whereas the analogous intermediate structure for 4-amino-1-butanol and GABA is γ-aminobutyraldehyde ...
