Bis-diazo-ethane, also known as diazomethane, is a highly reactive and toxic chemical compound with the formula (CH2N2)2. It is a colorless, volatile gas that is unstable and decomposes easily upon exposure to light or heat. Diazomethane is a powerful methylating agent, commonly used in organic synthesis to transfer a methyl group to various substrates, such as carboxylic acids, phenols, and amines, to form esters, ethers, and amines, respectively. Due to its hazardous nature and potential carcinogenic effects, its use is strictly regulated, and alternative, safer methylating agents are often preferred in laboratory settings.

5239-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5239-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.Calculate Digit Verification of CAS Registry Number 5239-05:
(6*5)+(5*2)+(4*3)+(3*9)+(2*0)+(1*5)=84
84 % 10 = 4
So 5239-05-4 is a valid CAS Registry Number.
