Methylphosphonothioic dibromide, also known as methylphosphonodithioic acid, is an organophosphorus compound with the chemical formula CH3Br2PS2. It is a colorless to pale yellow liquid that is soluble in organic solvents and has a pungent odor. methylphosphonothioic dibromide is primarily used as a flame retardant, particularly in plastics and textiles, due to its ability to release phosphorus and sulfur when heated, which helps to suppress combustion. It is also used as a pesticide and a chemical intermediate in the synthesis of other organophosphorus compounds. Methylphosphonothioic dibromide is considered to be toxic and has potential environmental and health risks, necessitating proper handling and disposal.

5827-24-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5827-24-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,2 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.Calculate Digit Verification of CAS Registry Number 5827-24:
(6*5)+(5*8)+(4*2)+(3*7)+(2*2)+(1*4)=107
107 % 10 = 7
So 5827-24-7 is a valid CAS Registry Number.
