1754-47-8 Usage
Chemical Properties
Clear colorless to yellow liquid
Uses
Different sources of media describe the Uses of 1754-47-8 differently. You can refer to the following data:
1. Dioctyl Phenylphosphonate is a taste sensor, or a constituent of a receptor membrane of a taste sensor use in tasting substances.
2. Dioctyl phenylphosphonate (DOPP) was used as plasticizer, in an experiment conducted for designing iron ion sensor based on functionalised ZnO (Zinc Oxide) nanorods. It was also used in Raman and UV-vis spectroscopic study, of polyaniline (PANI) membranes containing different amounts of a bulky lipophilic cationic additive, tridodecylmethylammonium chloride (TDMACl).
General Description
Dioctyl phenylphosphonate is a plasticizer.
Purification Methods
Purify it as described for diisooctyl phenylphosphonate and distil under high vacuum. [Beilstein 16 IV 1069.]
Check Digit Verification of cas no
The CAS Registry Mumber 1754-47-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,5 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1754-47:
(6*1)+(5*7)+(4*5)+(3*4)+(2*4)+(1*7)=88
88 % 10 = 8
So 1754-47-8 is a valid CAS Registry Number.

Possibilities for the mono- and diesterification of phenylphosphonic acid were evaluated considering the microwave(MW)-assisted direct esterification, and the alkylating esterification. It was found that regarding the monoesterification, the reaction with 15-fold alcohol excess in the presence of [bmim][BF4] additive utilizing MWs is superior than the approach by alkylation. At the same time, for the conversion of the monoester intermediate to the diester, the reaction with alkyl halides in the presence of triethylamine as the base, again under MW irradiation, was found to be the method of choice. Phosphonates with both identical and different alkoxy groups were made available.
