| Hazard Information | Back Directory | [Chemical Properties]
2-(p-Tolyl)-propionaldehyde has an intense, sweet, refreshing odor, similar to peppermint. | [Occurrence]
Has apparently not been reported to occur in nature | [Uses]
2-(4-Methylphenyl)propanal is used as a reactant in the asymmetric synthesis of α-branched homoallylic aldehydes. | [Preparation]
By reaction of α-terpinene and chromyl chloride in carbon disulfide and subsequent hydrolysis of the resulting cymenechromyl
chloride addition product; also by heating p-tolyl glycidic acid and water. | [Taste threshold values]
Taste characteristics at 10 ppm: green, woody, waxy and musty. |
| Safety Data | Back Directory | [Toxicity]
The acute oral LD50 value in rats was reported as 3.50 g/kg (2.40-4.60 g/kg) (Moreno, 1973). The acute dermal LD50 value in rabbits was reported as > 5 g/kg (Moreno, 1973). |
