Description

Isobutanethiol, also known as 2-Methyl-1-propanethiol, is a clear, colorless liquid with a pungent odor reminiscent of rotten cabbage. It is a naturally occurring compound found in trace amounts in certain foods and beverages and is also a byproduct of the petroleum refining process. This volatile and flammable substance is primarily utilized as a precursor in the synthesis of a variety of organic compounds, including flavors, fragrances, and insecticides, and serves multiple roles in different industries due to its unique properties.

Uses

Used in Flavor and Fragrance Industry:
Isobutanethiol is used as a flavoring agent for imparting specific scents and tastes to food products and beverages, capitalizing on its ability to contribute distinct aromatic notes even in minute quantities.
Used in Insecticide Production:
In the agricultural sector, Isobutanethiol is employed as a precursor in the synthesis of insecticides, leveraging its chemical properties to create compounds that effectively control and manage pest populations.
Used as a Scent Additive in Gas Industry:
Isobutanethiol is used as a scent additive in natural gas and propane to provide a detectable odor, ensuring the quick identification of gas leaks for safety purposes.
Used as a Corrosion Inhibitor in Mineral Oil Industry:
It serves as a corrosion inhibitor in mineral oil, protecting equipment and infrastructure from the damaging effects of corrosive compounds present in the oil.
Used as a Fuel Additive in Gasoline Production:
Isobutanethiol is utilized as a fuel additive in gasoline to enhance the fuel's performance characteristics, such as improving combustion efficiency and reducing emissions.
Given the volatility and flammability of Isobutanethiol, it is imperative to handle this compound with extreme caution to prevent potential explosive reactions with air and other chemicals, ensuring safety in all applications.

Check Digit Verification of cas no

The CAS Registry Mumber 513-44-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 513-44:
(5*5)+(4*1)+(3*3)+(2*4)+(1*4)=50
50 % 10 = 0
So 513-44-0 is a valid CAS Registry Number.
