503-76-4 Usage
General Description
2-Chloro-1-nitro-propane, also known as Chloropropyl nitrite, is a chemical compound with the formula C3H6ClNO2. It is a colorless to pale yellow liquid with a faint odor, and is mainly used as an intermediate in the production of agrochemicals and pharmaceuticals. Some of its properties include being flammable, with a flash point of 34°C, and having a melting point of -31°C. It is also classified as an irritant to the skin and eyes, and can cause respiratory irritation if inhaled. Additionally, it is considered harmful if swallowed, and can cause damage to organs through prolonged or repeated exposure. Due to its potential hazards, proper safety measures and protective equipment should be used when handling 2-Chloro-1-nitro-propane.
Check Digit Verification of cas no
The CAS Registry Mumber 503-76-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 503-76:
(5*5)+(4*0)+(3*3)+(2*7)+(1*6)=54
54 % 10 = 4
So 503-76-4 is a valid CAS Registry Number.

Visible Light-Induced Oxidative Chlorination of Alkyl sp3 C-H Bonds with NaCl/Oxone at Room Temperature

A visible light-induced monochlorination of cyclohexane with sodium chloride (5:1) has been successfully accomplished to afford chlorocyclohexane in excellent yield by using Oxone as the oxidant in H2O/CF3CH2OH at room temperature. Other secondary and primary alkyl sp3 C-H bonds of cycloalkanes and functional branch/linear alkanes can also be chlorinated, respectively, under similar conditions. The selection of a suitable organic solvent is crucial in these efficient radical chlorinations of alkanes in two-phase solutions. It is studied further by the achievement of high chemoselectivity in the chlorination of the benzyl sp3 C-H bond or the aryl sp2 C-H bond of toluene.
