Description
2-chloroethoxyacetonitrile, also known as 2-(2-chloroethoxy)acetonitrile, is an organic compound that serves as a key intermediate in the synthesis of various pharmaceuticals. It is characterized by its reactivity and functional groups, which make it a versatile building block in the development of new drugs.
Uses
Used in Pharmaceutical Industry:
2-chloroethoxyacetonitrile is used as a synthetic intermediate for the preparation of levocetirizine and its intermediates. Levocetirizine is a second-generation antihistamine used to treat symptoms of allergies such as sneezing, runny nose, and itchy eyes. 2-chloroethoxyacetonitrile's reactivity and functional groups make it an essential component in the synthesis of this medication, contributing to its effectiveness in alleviating allergic symptoms.
Check Digit Verification of cas no
The CAS Registry Mumber 31250-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,5 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31250-08:
(7*3)+(6*1)+(5*2)+(4*5)+(3*0)+(2*0)+(1*8)=65
65 % 10 = 5
So 31250-08-5 is a valid CAS Registry Number.

Complexes of macrocyclic compounds

Novel macrocyclic (monocyclic and bicyclic) compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.
