two hydroxides (OH-OH)
1,25- Dihydroxy vitamin D
It has importannce in preparation of dihydroxy benzene
The formula is C6H6O2 and it is 1,3-dihydroxy benzene.
¨Name】 4-Bromo-3,5-dihydroxy-N-methylbenzamide ¨【CAS Registry number】: 56375-85-0 ¨【Molecular Formula】: C8H8BrNO3 we can supply this one . but don't know what it use for
the alcohols have one hydroxyl group is called mono hydric alcohols
Talcapone, or 3,4-dihydroxy-4’-methyl-5-nitrobenzophenone, has the following function groups: methyl, alcohol (2 of them), carbonyl, and nitro groups. See the Web Links to the left for a diagram of the structure.
.(R)-3,4-dihydroxy-5-((S)- 1,2-dihydroxyethyl)furan-2(5H)-oneComplex to say the least.
1,3-dihydroxy propane. Propan-1,3-diol
Resorcinol is 1,3-dihydroxy benzene, it is acidic and two 'OH' groups make the system sufficiently polar so it is soluble in polar solvent water.

Propene + Br2 + hv ==> 3-Bromo-1-propene (free radical halogenation - allylic position is halogenated only)3-bromo-1-propene + OsO4 ==> 1,2 dihydroxy-3-bromo propane (or, you can also use MCPBA to create the epoxide and open it with mild acid or base, or you can use Br2 and H2O to create the halohydrin... lots of options here)1,2 dihydroxy-3-bromo propane + NaOH ==> 1,2,3 trihydroxy propane (glycerin aka glycerol)
