3-Chloro-1-idopropyne, also known as 3-chloro-1-iodo-1-propyne, is a halogenated alkyne with the chemical formula C3H2ClI. It is a colorless liquid with a pungent odor and is used as an intermediate in the synthesis of various organic compounds, particularly in pharmaceuticals and agrochemicals. The molecule consists of a triple bond between two carbon atoms, with one carbon atom bearing a chlorine atom and the other a iodine atom. Due to its reactivity, 3-chloro-1-idopropyne is sensitive to heat, light, and moisture, and should be stored and handled with caution. It is also considered a hazardous substance due to its potential health and environmental risks, necessitating proper safety measures during its use and disposal.

109-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109-71-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109-71:
(5*1)+(4*0)+(3*9)+(2*7)+(1*1)=47
47 % 10 = 7
So 109-71-7 is a valid CAS Registry Number.

An Improved Method for the Synthesis of 1-Iodoalkynes

Barluenga, Jose,Gonzalez, Jose M.,Rodriguez, Miguel A.,Campos, Pedro J.,Asensio, Gregorio

, p. 661 - 662 (1987)

A simple and general one-pot procedure for the synthesis of 1-iodoalkynes is described based on the reaction of terminal acetylenes with bis(pyridine)iodine(I) tetrafluoroborate in the presence of sodium methoxide.The method now reported is superior to the literature procedures in scope, handling, and often yield.
