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.

Copolymerization of Ethylene brassylate (cas 105-95-3) with δ-valerolactone towards isodimorphic random copolyesters with continuously tunable mechanical properties08/15/2019

Ring opening copolymerization of ethylene brassylate (EB) and δ-valerolactone (δ-VL) with various feeding ratios catalyzed by triphenyl bismuth was performed to prepare poly(ethylene brassylate-co-δ-valerolactone) copolyesters. The reactivity ratios of EB and δ-VL were firstly determined to ...detailed

Macrolactonization Reactions Driven by a Pentafluorobenzoyl Group**

Ciofini, Ilaria,Force, Guillaume,Leb?uf, David,Mayer, Robert J.,Perfetto, Anna

, p. 19843 - 19851 (2021)

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.
