General Description
3-Bromobutyronitrile, also known as 4-Bromo-2-butyronitrile, is a chemical compound with the formula C4H6BrN. It is a colorless to pale yellow liquid with a pungent odor. It is used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, as well as in the production of dyes, pigments, and other organic chemicals. 3-Bromobutyronitrile is a versatile building block in organic synthesis and is most commonly used in the manufacture of biologically active compounds, such as antibiotics, antifungal agents, and antiviral drugs. It is considered to be highly toxic and must be handled with caution.
Check Digit Verification of cas no
The CAS Registry Mumber 20965-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,6 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20965-20:
(7*2)+(6*0)+(5*9)+(4*6)+(3*5)+(2*2)+(1*0)=102
102 % 10 = 2
So 20965-20-2 is a valid CAS Registry Number.

A simple and general conjugate nucleophilic halogenation is presented. The THTO/halosilane combination has shown the ability to act as a nucleophilic halide source in the conjugate addition to a variety of Michael acceptors. In addition, a straightforward diastereoselective halogen installation using α,β-unsaturated acyloxazolidinones as platforms has been developed.
