285-69-8 Usage
Description
3,4-Epoxytetrahydrofuran, also known as 3,6-dioxabicyclo[3.1.0]hexane, is a clear yellow liquid with unique chemical properties. It is a versatile reagent derived from epoxides and is widely utilized in various industrial applications due to its ability to form degradable polymers.
Uses
Used in Polymer Industry:
3,4-Epoxytetrahydrofuran is used as a reagent for the production of various degradable polymers from epoxides. This application is particularly significant due to the growing demand for environmentally friendly materials that can break down over time, reducing the impact of plastic waste on the environment.
The use of a versatile dinuclear chromium catalyst in the process allows for the creation of polymers with specific properties tailored to various end-use applications, such as packaging materials, agricultural films, and biodegradable medical devices.
Check Digit Verification of cas no
The CAS Registry Mumber 285-69-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 285-69:
(5*2)+(4*8)+(3*5)+(2*6)+(1*9)=78
78 % 10 = 8
So 285-69-8 is a valid CAS Registry Number.
InChI:InChI=1/C4H6O2/c1-3-4(6-3)2-5-1/h3-4H,1-2H2/t3-,4+
