                • Chemische Eigenschaften white crystals with a honey-like odour
                • Chemische Eigenschaften Phenylacetic Acid occurs in Japanese peppermint oil, in neroli oil, and in traces in rose oils. It is a volatile aroma constituent of many foods (e.g., honey). It forms colorless crystals (mp 78°C) that have a honey odor.
                  The common route to phenylacetic acid is conversion of benzyl chloride into benzyl cyanide by reaction with sodium cyanide, followed by hydrolysis. Because of its intense odor, phenylacetic acid is added to perfumes in small quantities for rounding off blossom odors. Addition to fruit aromas imparts a sweet honey note.
                • Chemische Eigenschaften Phenylacetic acid has a sweet, animal, honey-like odor in dilute solution. The odor is persistent and disagreeable in concentrated solution. It has a sweet, honey-like flavor at high levels. At low levels, it is a sweetener.
                • Occurrence Reported found among the constituents of a few essential oils: tobacco, Rosa centifolia, Bulgarian rose, orange flowers absolute, neroli and Mentha arvensis of Japanese origin; also reported present among the volatile constituents of cocoa. Also reported found in guava, papaya, raspberry, strawberry, cooked potato, tomato, peppermint oil, pepper, rye bread, cheddar cheese, Swiss cheese, Gruyere cheese, boiled mutton, beer, cognac, cider, sherry, grape wines, white wine, sake, cocoa, tea, honey soy protein, passion fruit, starfruit, mango, mushroom, malt, wort, roasted chicory root, naranjilla fruit, choke berry, sea buckthorn and Chinese quince.
                • Verwenden Phenylacetic Acid is a flavoring agent that is crystalline (white, glis- tening), with unpleasant, persisting odor resembling geranium leaf and rose when diluted. it is soluble in most fixed oils and glycerin, slightly soluble in water, and insoluble in mineral oil. it is obtained by chemical synthesis. it is also termed a-toluic acid.
                • Verwenden Phenylacetic Acid is used in the synthesis of Diclofenac (D436450) and its metabolite 4'-Hydroxydiclofenac (H825225), which is the principal human metabolite of Diclofenac.
                • Definition ChEBI: A monocarboxylic acid that is toluene in which one of the hydrogens of the methyl group has been replaced by a carboxy group.
                • synthetische By the treatment of benzyl cyanide with dilute sulfuric acid and other processes.
                • Aroma threshold values Detection: 1 ppm
                • Taste threshold values Taste characteristics at 30 ppm: sweet, floral, chocolate, honey and tobacco.
                • Sicherheitsprofil Moderately toxic by ingestion, subcutaneous, and intraperitoneal routes. An experimental teratogen. Combustible liquid. Used in production of drugs of abuse. When heated to decomposition it emits acrid smoke and irritating fumes
                • l?uterung methode Crystallise the acid from pet ether (b 40-60o), isopropyl alcohol, 50% aqueous EtOH or hot water (m 77.8-78.2o). Dry it in vacuo. It can be distilled under a vacuum. [Beilstein 9 II 294, 9 III 2169.]
