Lithium Aluminium Hydride (LiAlH4), identified by CAS number 16853-85-3, is a cornerstone reagent in organic synthesis, celebrated for its potent reducing capabilities. However, its high reactivity also necessitates a thorough understanding of its properties, safe handling, and storage. As a leading manufacturer and supplier of fine chemicals, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to equipping chemists with the knowledge and resources they need to utilize LiAlH4 effectively and safely. This guide provides essential information for any professional seeking to buy LiAlH4.

Key Properties of Lithium Aluminium Hydride

LiAlH4 is a white to grayish crystalline powder. Its defining characteristic is its strong reducing power, stemming from the highly polar Al-H bond, which readily donates hydride ions (H⁻). This makes it capable of reducing a wide array of functional groups, including carbonyls (aldehydes, ketones, esters, carboxylic acids), nitriles, and amides. The general reaction involves the addition of hydride to the substrate, typically followed by protonation to yield the reduced product. Its solubility is good in anhydrous ethers like diethyl ether and THF, but it reacts vigorously with protic solvents (water, alcohols) and even atmospheric moisture.

Safety and Handling Precautions: A Priority

Due to its extreme reactivity, particularly with water, LiAlH4 must be handled with utmost care:

  • Anhydrous Conditions: Always use LiAlH4 under strictly anhydrous conditions. Reactions should be performed in dry glassware and with dry solvents.
  • Inert Atmosphere: Handling under an inert atmosphere (e.g., nitrogen or argon) is highly recommended to prevent contact with atmospheric moisture.
  • Controlled Addition: When adding LiAlH4 to a reaction mixture, or when quenching the reaction, it should be done slowly and carefully, often with cooling, to manage the exothermic reaction and hydrogen gas evolution.
  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including safety goggles, gloves, and a lab coat. Avoid generating dust, and ensure good ventilation.
  • Storage: Store LiAlH4 in tightly sealed containers in a cool, dry place, away from combustible materials and sources of ignition.

Understanding these precautions is vital when you purchase LiAlH4. As a responsible LiAlH4 supplier in China, NINGBO INNO PHARMCHEM adheres to strict safety standards in our own handling and provides necessary information to our clients.
