Description of LAH
Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula LiAlH4. It was discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Some related derivatives have been discussed for hydrogen storage.

What is ITHIUMAL?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is LAH which has developed particularly rapidly in recent years. Do you know about LAH?
- The official answerLithium aluminium hydride is a complex hydride with the molecular formula LiAlH4 and white or off-white crystals. Abbreviated as LAH, lithium aluminium hydride is a very important reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids and amides. Pure lithium aluminium hydride is a white crystalline solid, relatively stable below 120°C and in dry air, but decomposes explosively when exposed to water.
What’s the application of ITHIUMAL?
Used as a polymerization catalyst, reducing agent, jet engine fuel, also used in the synthesis of drugs. It can reduce aldehydes, ketones, acids, anhydrides, esters, lactones, quinones, and chlorides to alcohols, nitrile to Chemicalbook primary amines, and halogenated hydrocarbons to hydrocarbons. However, it usually cannot hydrogenate carbon-carbon double bonds. Uses an Extremely strong reducing agent. Widely used in pharmaceuticals, spices, pesticides and another fine organic synthesis.
