93-89-0 Usage


Ethyl benzoate, C9H10O2, is the ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents. As with many volatile esters, ethyl benzoate has a pleasant odor which could be described similar to wintergreen mint. It is a component of some artificial fruit flavors.

Chemical Properties

Ethyl benzoate is a colourless liquid that has a somewhat fruity odor similar to ylang-ylang, but milder than methyl benzoate. Soluble in ethanol, ethyl ether, petroleum ether, propylene glycol, mineral oil and most non-volatile oils, insoluble in water and glycerin.

Check Digit Verification of cas no

The CAS Registry Mumber 93-89-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93-89:
70 % 10 = 0
So 93-89-0 is a valid CAS Registry Number.

Ester Interchange Reaction Catalyzed by Lanthanoid Tri-2-propoxides

Okano, Tamon,Hayashizaki, Yugo,Kiji, Jitsuo

, p. 1863 - 1865 (1993)

Lanthanoid tri-2-propoxides (i)3>n Ln = La, Nd, Gd, Yb) are active catalysts for the interchange reaction of the alkoxyl groups between two kinds of esters.The La catalyst is the most active among them, and the activity is higher in nonpolar solvents than in polar ones.The La catalyst is applicable to the ring-opening polymerization of 6-hexanolide.

Electrochemical esterification via oxidative coupling of aldehydes and alcohols

Smeyne, Dylan,Verboom, Katherine,Bryan, Maria,LoBue, James,Shaikh, Abid

supporting information, (2021/03/26)

An electrolytic method for the direct oxidative coupling of aldehydes with alcohols to produce esters is described. Our method involves anodic oxidation in presence of TBAF as supporting electrolyte in an undivided electrochemical cell equipped with graphite electrodes. This method successfully couples a wide range of alcohols to benzaldehydes with yields ranging from 70 to 90%. The protocol is easy to perform at a constant voltage conditions and offers a sustainable alternative over conventional methods.

Remarkably Efficient Iridium Catalysts for Directed C(sp2)-H and C(sp3)-H Borylation of Diverse Classes of Substrates

Chattopadhyay, Buddhadeb,Hassan, Mirja Md Mahamudul,Hoque, Md Emdadul

supporting information, p. 5022 - 5037 (2021/05/04)

Here we describe the discovery of a new class of C-H borylation catalysts and their use for regioselective C-H borylation of aromatic, heteroaromatic, and aliphatic systems. The new catalysts have Ir-C(thienyl) or Ir-C(furyl) anionic ligands instead of the diamine-type neutral chelating ligands used in the standard C-H borylation conditions. It is reported that the employment of these newly discovered catalysts show excellent reactivity and ortho-selectivity for diverse classes of aromatic substrates with high isolated yields. Moreover, the catalysts proved to be efficient for a wide number of aliphatic substrates for selective C(sp3)-H bond borylations. Heterocyclic molecules are selectively borylated using the inherently elevated reactivity of the C-H bonds. A number of late-stage C-H functionalization have been described using the same catalysts. Furthermore, we show that one of the catalysts could be used even in open air for the C(sp2)-H and C(sp3)-H borylations enabling the method more general. Preliminary mechanistic studies suggest that the active catalytic intermediate is the Ir(bis)boryl complex, and the attached ligand acts as bidentate ligand. Collectively, this study underlines the discovery of new class of C-H borylation catalysts that should find wide application in the context of C-H functionalization chemistry.
