It is a derivative of phosphoric acid, specifically a phosphorodichloridate ester, and is characterized by the presence of two chlorine atoms attached to an isopropyl group and a 4-methylphenyl group. DCIPMS is a colorless to pale yellow liquid that is soluble in organic solvents. It is used as a reagent in organic synthesis, particularly in the preparation of various phosphorus-containing compounds. Due to its reactivity, it is important to handle O-(α,α'-Dichlorisopropyl)-O-(4-methylphenyl)-schwefligsaeureester with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.
The CAS Registry Mumber 3698-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3698-77: (6*3)+(5*6)+(4*9)+(3*8)+(2*7)+(1*7)=129 129 % 10 = 9 So 3698-77-9 is a valid CAS Registry Number.
