Benzaldehyde dimethyl acetal

Chemical properties

Clear colorless liquid

Chemical properties

Benzaldehyde dimethyl acetal has a sweet, floral note; also reminiscent of almond

Occurrence

Reported found in rhubarb and potato.

The Uses of Benzaldehyde dimethyl acetal

Benzaldehyde dimethyl acetal used as an effective reagent for the construction of selenocarbonyl compounds.

The Uses of Benzaldehyde dimethyl acetal

Benzaldehyde dimethyl acetal is suitable for use in the synthesis of 4,6-dihydroxy sugar, required for the total synthesis of Porphyromonas gingivalis 381 derived lipid A. It may be used in the preparation of 1-O-methyl-2,3-di-O-galloyl-β-D-glucose.

The Uses of Benzaldehyde dimethyl acetal

Benzaldehyde dimethyl acetal may be used as an analytical reference standard for the quantification of the analyte in fresh and canned fish and Cinnamomum zeylanicum using gas-chromatography coupled to mass spectrometry (GC-MS).

Preparation

From benzaldehyde and methanol in the presence of calcium chloride and HCl; from benzaldehyde and tetramethylorthosilicate in the presence of anhydrous HCl in methanol

Preparation

A mixture of ethylenediamine (1.2 g, 20 mmol), Ph3SbO (1.0 mmol), and P4S10 (2.0 mmol) was autoclaved under a pressure of CO2 (4.9 MPa). Imidazolidinone was isolated by column chromatography (silica gel; eluent: ethyl acetate/hexane, 1:1, v/v); yield 1.5 g (85%).

Definition

ChEBI: (Dimethoxymethyl)benzene is a benzyl ether.

Taste threshold values

Taste characteristics at 25 ppm: green, nutty, brown and sweet

General Description

The abstraction of α-hydrogen atoms from benzaldehyde dimethyl acetal by active bromine at 80°C has been investigated.

Safety Profile

Moderately toxic by ingestion. A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
