625-67-2 Usage
General Description
2,4-Dichloropentane is a chemical compound with the formula C5H10Cl2. It is a colorless liquid with a pungent odor, and is classified as a chlorinated hydrocarbon. 2,4-Dichloropentane is commonly used as an intermediate in the synthesis of other organic compounds and as a solvent in various industrial processes. It is also used as a reagent in organic chemistry reactions, particularly in the formation of carbon-carbon bonds. However, it is important to note that 2,4-Dichloropentane is toxic and should be handled with caution, as it can cause irritation to the eyes, skin, and respiratory tract upon exposure. Additionally, it may have harmful effects on the environment and aquatic organisms if released into the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 625-67-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 625-67:
(5*6)+(4*2)+(3*5)+(2*6)+(1*7)=72
72 % 10 = 2
So 625-67-2 is a valid CAS Registry Number.

Flexible molecules with defined shape XI[≠]. - Conformer equilibria in 2,4-disubstituted pentane derivatives
Hoffmann, Reinhard W.,Stenkamp, Dirk,Trieselmann, Thomas,G?ttlich, Richard

2,4-Disubstituted penfanes are molecules which adopt essentially only two conformations. Substituents have been varied in order to find those which lead to a strong preference of the conformer equilibrium. Studying 2- substituted 4-methylpentanes 3 and 4-benzyloxypentanes 12, it has been shown that substituent effects on the conformer equilibria are not additive, as would be expected on the grounds of steric effects alone. Rather, interactions between polar groups reinforce the bias of the conformer equilibria. When applied to 2,4-disubstituted pentanes, substituents such as chloro or phthalimido shift the conformer equilibrium to the side of the gg conformer with preferences exceeding 90%.
