105-95-3 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 105-95-3 differently. You can refer to the following data:
1. Colorless to pale yellow transparent liquid
2. Ethylene brassylate is an artificial
fragrance material, with a sweetish, slightly fatty, musk odor. Similarly to the
aforementioned 1,12-dodecanedioic ester compound, the ester is obtained by
depolymerization of the corresponding polyester. Traditionally, brassylic acid
(1,13-tridecanedioic acid) is prepared by ozonolysis of erucic acid
3. Ethyl.brassylate.has.musk-like.character.and.sweet.odor
Occurrence
Has apparently not been reported to occur in nature.
Preparation
By esterification of brassylic acid.
Taste threshold values
Taste characteristics at 0.5%: musky, sweet, powdery, floral, vanilla and perfumey
General Description
Ethylene brassylate is macrocylic compound mainly used as a fragrance ingredient for its musk-like odor.
Flammability and Explosibility
Nonflammable
Trade name
Musk T? (Takasago), MC-5 (Soda Aromatic)
Check Digit Verification of cas no
The CAS Registry Mumber 105-95-3 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 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105-95:
(5*1)+(4*0)+(3*5)+(2*9)+(1*5)=43
43 % 10 = 3
So 105-95-3 is a valid CAS Registry Number.

Macrolactonization Reactions Driven by a Pentafluorobenzoyl Group**

Macrolactones constitute a privileged class of natural and synthetic products with a broad range of applications in the fine chemicals and pharmaceutical industry. Despite all the progress made towards their synthesis, notably from seco-acids, a macrolactonization promoter system that is effective, selective, flexible, readily available, and, insofar as possible, compatible with manifold functional groups is still lacking. Herein, we describe a strategy that relies on the formation of a mixed anhydride incorporating a pentafluorophenyl group which, due to its high electronic activation enables a convenient access to macrolactones, macrodiolides and esters with a broad versatility. Kinetic studies and DFT computations were performed to rationalize the reactivity of the pentafluorophenyl group in macrolactonization reactions.
