General Description
3,5-DIMETHYL-3-HEXANOL is a chemical compound with the molecular formula C8H18O. It is a branched-chain alcohol, with a six-carbon main chain and two methyl (CH3) groups attached to the third and fifth carbon atoms. 3,5-DIMETHYL-3-HEXANOL is commonly used in the production of flavors and fragrances due to its pleasant odor. It is also used as a solvent and as an intermediate in the synthesis of other organic compounds. 3,5-DIMETHYL-3-HEXANOL is a colorless liquid with a slightly sweet, floral aroma and is known to be flammable. It should be handled and stored with proper safety precautions and in accordance with regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 4209-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4209-91:
(6*4)+(5*2)+(4*0)+(3*9)+(2*9)+(1*1)=80
80 % 10 = 0
So 4209-91-0 is a valid CAS Registry Number.

Effect of the Structure of Unsaturated Aliphatic Alcohols on the Hydrogenation Rate over Pd-Ru Membrane Catalyst
Karavanov, A. N.,Gryaznov, V. M.,Batyrev, I. G.,Olenina, E. G.
, p. 739 - 743 (2007/10/02)
It is shown that the rate of hydrogenation of substituted propargyl and allyl alcohols, as measured in the liquid phase on a membrane Pd-Ru alloy catalyst is described by the two-parameter Taft equation, which accounts for the induction and steric substituent effects.A positive induction effect of the substituent group promotes the reaction, whereas a negative one slows it down; an enhancement in the steric factor decreases the rate of conversion.Both induction and steric effects are stronger in reactions with ethylenic rather than acetylenic alcohols and for trans rather than cis isomers.
