Dimethyl heptylphosphonate, also known as dimethyl 2-heptylphosphonate, is an organophosphorus compound with the chemical formula C7H17O2P. It is a colorless liquid that is soluble in organic solvents and has a molecular weight of 170.18 g/mol. dimethyl heptylphosphonate is primarily used as a flame retardant, plasticizer, and stabilizing agent in various industrial applications, including the production of plastics, rubber, and textiles. It is also employed as an intermediate in the synthesis of other organophosphorus compounds. Due to its phosphorus content, dimethyl heptylphosphonate exhibits unique properties, such as its ability to chelate metal ions and its potential use in the development of new materials with enhanced flame resistance and thermal stability.

Check Digit Verification of cas no

The CAS Registry Mumber 6172-70-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,7 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6172-70:
(6*6)+(5*1)+(4*7)+(3*2)+(2*7)+(1*0)=89
89 % 10 = 9
So 6172-70-9 is a valid CAS Registry Number.

supporting information, p. 4755 - 4760 (2020/10/06)

A metal-free C?P bond cleavage reaction is described herein. Phosphoramides, a phosphine source, can react with alcohols to produce phosphonate and phosphinate derivatives in the presence of a disulfide. P?H2, P-alkyl, and P,P-dialkyl phosphoramides can be used as substrates to obtain the corresponding pentavalent phosphine products. (Figure presented.).
