6632-88-8

Diethyl (2-hydroxypropan-2-yl)phosphonate, also known as DEHP, is a colorless, viscous liquid with the chemical formula C8H19O4P. It is an organophosphorus compound widely used as a plasticizer, primarily in the production of polyvinyl chloride (PVC) products, to increase their flexibility and durability. DEHP is also employed in the manufacturing of adhesives, sealants, and lubricants. However, it has raised concerns due to its potential health and environmental impacts, as it can leach out of products and has been classified as an endocrine disruptor. As a result, its use has been restricted or banned in certain applications and regions.

6632-88-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6632-88-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6632-88:
(6*6)+(5*6)+(4*3)+(3*2)+(2*8)+(1*8)=108
108 % 10 = 8
So 6632-88-8 is a valid CAS Registry Number.

The preparation of dialkyl 1-hydroxyalkylphosphonates in the reaction of trialkyl phosphites with oxonium salts derived from aldehydes or ketones

Goldeman, Waldemar,Soroka, Miroslaw

, p. 3019 - 3024 (2008/02/08)

The reaction of trialkyl phosphites with aldehydes or ketones in the presence of hydrogen chloride gives dialkyl 1-hydroxyalkylphosphonates via Arbusov-like reaction of oxonium salts derived from aldehydes or ketones. This reaction is a very convenient instant method for the preparation of dialkyl 1-hydroxyalkylphosphonates with a good yield as an alternative to the well-known Abramov reaction.
