Использование
3-(Methylthio)propionaldehyde, is used as food flavour ,for making Baked food, spices, soft drinks, candy. It is also used as an intermediate. It has wide applications in organic synthesis as solvents as well as reagents. They are used in the synthesis of specific compound classes include agricultural chemical, property-enhancing additives, pharmacological drugs, chemical resistant polymers, detergents, and rubber antioxidants. Some examples of aliphatic and aromatic thioethers found in flavouring agents
Подготовка
By transamination and decarboxylation of various amino acids; by oxidation of the alcohol
Общее описание
A colorless to amber liquid with an extremely foul and persistent odor. Slightly soluble in water and denser than water. Contact may slightly irritate skin, eyes and mucous membranes. Moderately toxic. Used as a food additive.
Реакции воздуха и воды
Slightly soluble in water.
Профиль реактивности
Organosulfides, such as 3-(Methylthio)propionaldehyde, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Угроза здоровью
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Пожароопасность
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Профиль безопасности
Moderately toxic by
ingestion. When heated to decomposition it
emits toxic vapors of SOx.
Синтез
3-(Methylthio)propionaldehyde's synthesis method is as follows: (in Nature) by transamination and decarboxylation of various amino acids
