Dicyclopropyl-carbonyl-phenyl-phosphat, also known as DCPCP, is a phosphorus-containing organophosphorus compound with the chemical formula C15H15O3P. It is a colorless to pale yellow crystalline solid that is soluble in organic solvents. DCPCP is primarily used as a flame retardant and plasticizer in various polymer materials, such as polyvinyl chloride (PVC) and polyurethane foams. It functions by releasing phosphorus-based compounds when exposed to heat, which can interrupt the combustion process and slow down the spread of fire. Due to its effectiveness and low toxicity, DCPCP has become a popular choice for flame retardant applications in construction, electronics, and automotive industries. However, it is essential to handle and dispose of DCPCP responsibly, as it may have potential environmental and health impacts.
The CAS Registry Mumber 6612-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,1 and 2 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6612-65: (6*6)+(5*6)+(4*1)+(3*2)+(2*6)+(1*5)=93 93 % 10 = 3 So 6612-65-3 is a valid CAS Registry Number.
