The influence of parameters such as reaction time and cofactor, substrate, co-substrate 2-propanol and Amyl cinnamyl alcohol (A-036) Your patch testing results indicate that you have a contact allergy to Amyl cinnamyl alcohol. It is important that you familiarize yourself with this chemical and take steps to avoid coming in contact with it. What is Amyl cinnamyl alcohol and where is it found? Described here is the nucleophilic substitution of a hydroxyl group, in cinnamyl alcohol, by fluorine, and analysis of the product using 19-F NMR spectroscopy.

BACKGROUND: Cinnamyl alcohol and cinnamal are frequent fragrance contact allergens. Both are included in the European baseline fragrance mix I, which is used for screening of contact allergy in dermatitis patients. NMR standard samples of expected cinnamon parts such as coumarin 1, cinnamyl alcohol 2, cinnamaldehyde 3, cinnamic acid 4, eugenol 5, and cinnamyl acetate 6, were formulated by dissolving about 90 to 150 mg of each in 2 mL CDCl 3 and then transferring 600 uL of each to 5 mm NMR tubes.

Cinnamyl alcohol causes Friedel Crafts alkylation of bulky aromatic compound 2,4-di-tert-butylphenol using mesoporous aluminosilicate as catalyst. Cinnamyl alcohol undergoes partial oxidation in air to form cinnamaldehyde over a series of Bi-Pt/alumina catalysts. Cinnamyl alcohol is used in perfumery and in deodorant compositions. Cinnamyl alcohol is an α,β-unsaturated alcohol that can be used as a flavoring agent and a fragrance ingredient. Application Building block - Cinnamic alcohol is a building block for cinnamyl esters, via reaction with carboxylic acids or carboxylic acid derivatives. Some of the cinnamyl esters are used as fragrance components.

This experiment brings important innovations to the teaching of experimental organic chemistry at the undergraduate level. The fluorination of cinnamyl alcohol requires only a mild fluorinating agent and so it provides the student with Cinnamyl alcohol REACH pre-registration, Other, Cosmetic Products Regulation, Annex III - Restricted Substances, Annex II, Sec III - Allergenic Fragrances Banned/Restricted in Toys gamma-Phenylallyl alcohol NMR standard samples of expected cinnamon parts such as coumarin 1, cinnamyl alcohol 2, cinnamaldehyde 3, cinnamic acid 4, eugenol 5, and cinnamyl acetate 6, were formulated by dissolving about 90 to 150 mg of each in 2 mL CDCl 3 and then transferring 600 uL of each to 5 mm NMR tubes.
