102-22-7 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 102-22-7 differently. You can refer to the following data:
1. It is a yellow liquid with a mild rose odor
and a secondary honey note. It is used as a fixative in rose compositions and
heavy perfumes.
2. Geranyl phenylacetate has a honey- and rose-like odor.
Occurrence
Has apparently not been reported to occur in nature.
Uses
Geranyl Phenylacetate is a flavoring agent that is a yellow liquid
with an odor resembling honey and roses. miscible in alcohol, chloro-
form, and ether, and insoluble in water, it may contain other iso-
meric and closely related terpenic esters. it is obtained by chemical
synthesis.
Preparation
By the esterification of geraniol with phenylacetyl chloride.
Aroma threshold values
Aroma characteristics at 2.0%: foral, powdery, rosy, honey and dried fruit-like with balsamic undernotes.
Taste threshold values
Taste characteristics at 35 ppm: foral, rosy, honey and green with fatty, fruity nuances.
Flammability and Explosibility
Notclassified
Safety Profile
Low toxicity by
ingestion and sktn contact. Combustible
liquid. When heated to decomposition it
emits acrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 102-22-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 102-22:
(5*1)+(4*0)+(3*2)+(2*2)+(1*2)=17
17 % 10 = 7
So 102-22-7 is a valid CAS Registry Number.

Gd(OTf)3-catalyzed synthesis of geranyl esters for the intramolecular radical cyclization of their epoxides mediated by titanocene(III)
Garca Santos, William H.,Puerto Galvis, Carlos E.,Kouznetsov, Vladimir V.

A selective and mild method for the esterification of a variety of carboxylic acids with geraniol is developed. We demonstrated that the use of triphenylphosphine, I2, 2-methylimidazole or imidazole and a catalytic amount of Gd(OTf)3 resulted to be more active than the previous protocols, providing a 16-membered library of geranyl esters in higher yields and in shorter reaction times. The use of essential oil of palmarosa (Cymbopogon martinii), enriched with geraniol, as a raw material for the synthesis of the target compounds complemented and proved how sustainable and eco-friendly this protocol is. Finally, the selective 6,7-epoxidation of the obtained geranyl esters led us to study their regio-controlled radical cyclization mediated by titanocene(iii) for the synthesis of novel (8-hydroxy-9,9-dimethyl-5-methylene cyclohexyl)methyl esters in moderate yields and with excellent stereoselectivities.
A USEFUL METHOD FOR SELECTIVE ACYLATION OF ALCOHOLS USING 2,2'-BIPYRIDYL-6-YL CARBOXYLATE AND CESIUM FLUORIDE
Mukaiyama, Teruaki,Pai, Fong-Chang,Onaka, Makoto,Narasaka, Koichi
, p. 563 - 566 (2007/10/02)
Primary and secondary alcohols are acylated under mild conditions by the of use 2,2'-bipyridyl-6-yl carboxylates and cesium fluoride.Furthermore, the reaction is successfully applied to selective acylation of a primary carbinol group of diols containing primary and secondary carbinol groups or exclusive O-acylation of aromatic amino alcohols.
