187-29-1 Usage
General Description
1,2,4,5-Diepoxypentane, also known as tetraglycidylethylene diamine, is a chemical compound that has two epoxy functional groups and is used as a cross-linking agent in the production of epoxy resins. It is a colorless liquid with a faint odor and is considered to be a hazardous substance due to its toxicity and potential for causing skin and eye irritation. 1,2,4,5-Diepoxypentane is also used in the manufacture of plastics, adhesives, and coatings, and is known for its high thermal stability and resistance to chemicals. It is important to handle this chemical with care and in compliance with safety regulations to prevent any potential health and environmental hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 187-29-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 187-29:
(5*1)+(4*8)+(3*7)+(2*2)+(1*9)=71
71 % 10 = 1
So 187-29-1 is a valid CAS Registry Number.

1,4-Addition of azide to trans-diepoxycyclopentane with solvent participation
Farkas, Frederic,Sequin, Urs,Bur, Daniel,Zehnder, Margareta
, p. 103 - 110 (2007/10/10)
The reaction of trans-diepoxycyclopentane with azide leads in methanol to the expected azidohydrins; a 1,4-adduct with a 'central' epoxy group is also formed. When the reaction is carried out in acetone/water 1:1, an additional product, which is the acetonide of an azido-trihydoxycyclopentane, is observed. This compound must have been formed by participation of the solvent followed by cyclization.
