General Description

1,2-dibromocyclopentane is an organic compound with the chemical formula C5H8Br2. It is a colorless liquid that is insoluble in water but soluble in organic solvents. It is primarily used as a reagent in organic synthesis, particularly in the preparation of other organic compounds. 1,2-dibromocyclopentane is a halogenated compound, meaning it contains bromine atoms, and is highly reactive due to the presence of the bromine atoms. It is important to handle this compound with caution as it is a potentially hazardous material, and it is important to follow safety protocols when working with it.

Check Digit Verification of cas no

The CAS Registry Mumber 10230-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,3 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10230-26:
(7*1)+(6*0)+(5*2)+(4*3)+(3*0)+(2*2)+(1*6)=39
39 % 10 = 9
So 10230-26-9 is a valid CAS Registry Number.

VALISA: A new procedure for total lineshape analysis of NMR spectra. Conformational analysis of trans-1,2-dibromocyclopentane

Zubkov,Golotvin,Chertkov

, p. 1222 - 1230 (2002)

A new strategy of total lineshape analysis of the multiplet structure of NMR spectra was proposed and a VALISA program was developed to implement the computational procedure. Evaluation of the new technique taking a solution of several test problems and the complete analysis of the 1H NMR spectrum of trans-1,2-dibromocyclopentane as examples showed its high efficiency. Using a complete set of vicinal spin-spin coupling constants, detailed conformational analysis of this molecule was carried out and a more correct model for the description of conformational interconversions of the five-membered cycles was proposed. Conformational behavior of trans-1,2-dibromocyclopentane molecule can be reasonably described assuming large-amplitude molecular vibrations along a sector of the pseudorotation path, containing mostly diequatorial conformations.

Method for preparing o-dibromo compounds from olefins

-

Paragraph 0012; 0013, (2018/09/28)

The invention relates to a method for preparing o-dibromo compounds from olefins, and the structural formulae of the o-dibromo compounds are as follows. The method comprises the following steps: dropwise adding a dichloromethane solution of dimethyl sulfoxide (1.5 equiv) into a dichloromethane solution of oxalyl bromide (1.5 equv) at a temperature of -10 DEG C, then dropwise adding a raw materialolefin, and then recovering the temperature to room temperature or carrying out heating to 30-40 DEG C, carrying out a reaction to obtain the corresponding o-dibromo compounds, wherein the yield is ina range of 79-97%.
