2-Trifluoromethyl-1,4-phenylendiisocyanat, also known as 2,5-difluorophenyl diisocyanate, is an organic compound with the chemical formula C9H3F3N2O2. It is a colorless to pale yellow liquid that is widely used in the production of polyurethane foams, elastomers, and coatings due to its high reactivity and versatility. This chemical is characterized by its two isocyanate groups attached to a 2-trifluoromethyl-1,4-phenylene core, which provides unique properties such as enhanced thermal stability and resistance to hydrolysis. It is also known for its low toxicity compared to other diisocyanates, making it a preferred choice in various industrial applications. However, it is important to handle this chemical with care, as it can cause irritation to the eyes, skin, and respiratory system, and is classified as a hazardous substance.
The CAS Registry Mumber 1483-52-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 3 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1483-52: (6*1)+(5*4)+(4*8)+(3*3)+(2*5)+(1*2)=79 79 % 10 = 9 So 1483-52-9 is a valid CAS Registry Number.
