Diazo-(2,5-dimethyl-phenyl)-methan, also known as 2,5-dimethylbenzenediazomethane, is an organic compound with the chemical formula C9H10N2. It is a yellow crystalline solid that is sensitive to light and heat, and it decomposes upon exposure to air. Diazo-(2,5-dimethyl-phenyl)-methan is a derivative of benzene, featuring two methyl groups at the 2 and 5 positions, and a diazomethane group attached to the phenyl ring. It is used as a reagent in organic synthesis, particularly in the preparation of various heterocyclic compounds and as a precursor for the synthesis of pharmaceuticals and agrochemicals. Due to its instability, it must be handled with care and stored under controlled conditions to prevent decomposition.

769-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 769-73-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 769-73:
(5*7)+(4*6)+(3*9)+(2*7)+(1*3)=103
103 % 10 = 3
So 769-73-3 is a valid CAS Registry Number.
