For chemists and engineers involved in organic synthesis, a deep understanding of reagent properties and handling procedures is paramount. Lithium Tri-tert-butoxyaluminum Hydride (LTBA), CAS 17476-04-9, is a specialized reducing agent that offers unique advantages, but like many reactive chemicals, requires careful consideration. As a professional chemical supplier, we aim to provide comprehensive technical insights to our clients, enabling them to utilize LTBA effectively and safely.

Key Chemical Properties of LTBA

Lithium Tri-tert-butoxyaluminum Hydride (LiAlH[OC(CH3)3]3) is characterized by its moderated reactivity, a direct result of the bulky tert-butoxy groups attached to the aluminum center. This steric hindrance significantly reduces its nucleophilicity compared to Lithium Aluminum Hydride (LAH), making it a milder reducing agent. The common appearance is a white powder, although it is often supplied as a solution in solvents like Tetrahydrofuran (THF) or Diglyme, typically at concentrations around 1.0 M. Its molecular weight is 254.27 g/mol. Key properties relevant to its use include:

  • Solubility: Soluble in organic solvents such as THF, diethyl ether, and diglyme.
  • Stability: Stable in dry air but hydrolyzes slowly in moist air. It is highly sensitive to moisture and should be handled under an inert atmosphere (e.g., nitrogen or argon).
  • Reactivity: Reacts violently with water and protic solvents. Incompatible with alcohols and strong acids.
  • Melting/Boiling Point: While the solid form has a high melting point (often >300°C with decomposition), solutions have properties dictated by the solvent.

Understanding these properties is crucial for procurement managers and R&D scientists when planning reaction conditions and storage. We ensure our products meet strict purity standards (≥99%) for optimal performance.

Preparation and Safety Considerations

LTBA is typically prepared by reacting Lithium Aluminum Hydride with tert-butanol in an ethereal solvent. The reaction requires strict control over conditions to ensure product purity and yield. When handling LTBA, whether in solid or solution form, rigorous safety protocols are essential. This includes:

  • Working in a well-ventilated fume hood.
  • Using appropriate personal protective equipment (PPE), such as gloves, safety glasses, and lab coats.
  • Ensuring all glassware and equipment are dry.
  • Storing the reagent in tightly sealed containers under an inert atmosphere, away from moisture and heat.

As a responsible supplier, we provide comprehensive Safety Data Sheets (SDS) with every order, detailing hazards, handling, storage, and emergency procedures. These documents are vital for anyone looking to buy and use this chemical safely.
