616-42-2 Usage
Description
Dimethyl sulfite is a clear, colorless to pale yellow liquid that serves as an insect repellent and has been experimentally identified as a mutagenic agent. It is known for its conformational selective aggregation and has been studied using matrix-isolation Fourier transform infrared spectroscopy.
Uses
Used in Organic Synthesis:
Dimethyl sulfite is used as a reagent in organic synthesis, contributing to the formation of various chemical compounds due to its unique properties.
Used in Polymer Industry:
Dimethyl sulfite is used as an additive in some polymers to prevent oxidation, enhancing the stability and durability of the materials.
Used in Energy Storage:
As a potentially useful high energy battery electrolyte solvent, dimethyl sulfite contributes to the development of more efficient and powerful energy storage solutions.
Used in Insect Repellent Applications:
Due to its insect repellent properties, dimethyl sulfite is utilized in the creation of products designed to keep insects away, providing protection against bites and potential diseases they may carry.
Used in Mutagenesis Research:
Dimethyl sulfite's mutagenic properties make it a valuable compound for research in the field of mutagenesis, where it can be used to study genetic mutations and their effects on organisms.
Preparation
Dimethyl sulfite is prepared from a 1:2 ratio of thionyl chloride and methanol. The reaction can be catalyzed by tertiary amine bases and likely proceeds via the chlorosulfinate (MeOS(O)Cl), this intermediate will exist only fleetingly in the presence of methanol and as such its decomposition to methyl chloride and sulfur dioxide (via the slower SNi mechanism) is not observed to any great extent. SOCl2 + 2 CH3OH → (CH3O)2SO + 2 HCl
Check Digit Verification of cas no
The CAS Registry Mumber 616-42-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 616-42:
(5*6)+(4*1)+(3*6)+(2*4)+(1*2)=62
62 % 10 = 2
So 616-42-2 is a valid CAS Registry Number.
