2,2,4,4-Tetraethoxy-6,6-diphenylcyclotriphosphazatrien, also known as DEPC, is a cyclic phosphazene compound with the chemical formula (C2H5O)4P3N3C6H5. It is a colorless, viscous liquid that is soluble in organic solvents. DEPC is widely used as a silylating agent in organic synthesis, particularly for the protection of hydroxyl groups in alcohols and phenols. It is also employed as a coupling agent in the formation of various phosphazene polymers and as a flame retardant in plastics and textiles. Due to its reactivity and potential health hazards, DEPC is handled with caution and is considered a hazardous substance.
The CAS Registry Mumber 6099-35-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,9 and 9 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6099-35: (6*6)+(5*0)+(4*9)+(3*9)+(2*3)+(1*5)=110 110 % 10 = 0 So 6099-35-0 is a valid CAS Registry Number.
