Dodecyl methyl methylphosphonate, also known as C12H27O3P, is an organophosphorus compound that is widely used as a flame retardant and plasticizer. It is a colorless liquid with a molecular weight of 242.32 g/mol. This chemical is derived from the reaction of dodecyl alcohol with methylphosphonic acid, resulting in a product that exhibits excellent thermal stability and low toxicity. Due to its ability to enhance the flame resistance of various materials, dodecyl methyl methylphosphonate is commonly employed in the production of plastics, textiles, and other synthetic materials. Its low toxicity and environmental persistence have made it a preferred choice over more hazardous flame retardants. However, it is important to handle this chemical with care, as it can cause irritation to the eyes, skin, and respiratory system if not properly managed.

Check Digit Verification of cas no

The CAS Registry Mumber 4844-37-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,4 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4844-37:
(6*4)+(5*8)+(4*4)+(3*4)+(2*3)+(1*7)=105
105 % 10 = 5
So 4844-37-5 is a valid CAS Registry Number.

A convenient method to access long-chain and functionalised mixed methylphosphonate esters and their application in the synthesis of ionic liquids

Sachnov, Swetlana J.,Schulz, Peter S.,Wasserscheid, Peter

, p. 11234 - 11236 (2011)

A new method to synthesise long-chain and functionalised methylphosphonate esters and the corresponding ionic liquids is reported. The synthesis comprises the formation of dialkyl methylphosphonate esters in a SN2 reaction followed by the use of these esters as alkylating agents to form the corresponding, new alkyl methylphosphonate ILs.
