23511-70-8 Usage
General Description
2-Phenoxyethyl butyrate is a chemical compound that falls under the class of phenoxyethanol esters. It is commonly used as a fragrance ingredient in various personal care and cosmetic products due to its pleasant floral scent. This chemical is also used as a flavoring agent in food products. It is a colorless to light yellow liquid with a citrus-like odor and is insoluble in water. 2-Phenoxyethyl butyrate is known for its low toxicity and is considered safe for use in cosmetics and personal care products when used in accordance with regulations and guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 23511-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,5,1 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23511-70:
(7*2)+(6*3)+(5*5)+(4*1)+(3*1)+(2*7)+(1*0)=78
78 % 10 = 8
So 23511-70-8 is a valid CAS Registry Number.

Reestimation of the Taft's substituent constant of the pentafluorophenyl group
Korenaga, Toshinobu,Kadowaki, Koichi,Ema, Tadashi,Sakai, Takashi
, p. 7340 - 7343 (2007/10/03)
The Taft's substituent constant of the pentafluorophenyl group (σ*C6F5)) was reestimated to be 1.50 by correlation between IR spectral data (vC=O) and σ* constants for a series of esters (involving the pentafluorobenzyl group) of 3-phenylpropanoic acid and butanoic acid. The possibility of the disturbance of the correlation by the intramolecular π-π interaction between C 6F5 and C6H5 groups in pentafluorobenzyl 3-phenylpropanoate was excluded by ab initio and DFT calculations of the stable conformations and their carbonyl frequencies. The reestimated σ* (C6F5) value was used for calculation of the pKa value of pentafluorobenzyl alcohol [14.5 (or 14.3)].
