Overview
Ammonia borane (CAS 13774-81-7 ), also known as borazane, is a solid hydrogen storage compound that releases hydrogen gas at relatively low temperatures through controlled decomposition.
It functions as a chemical hydrogen carrier and reducing agent in research, specialty synthesis, and emerging energy applications. In hydrogen storage and fuel cell development, it serves as a solid-state hydrogen source.
This material enables compact, high-capacity storage systems for aerospace and defense platforms where weight and volume constraints are critical. Pharmaceutical and fine chemical manufacturers use it as a selective reducing agent.
It is utilized in the synthesis of complex intermediates, particularly where milder conditions are required than conventional borohydride reagents offer. In electronics, it supports the deposition of boron-containing thin films.
The compound acts as a precursor in chemical vapor deposition processes for semiconductor fabrication. Industrial cleaning formulations targeting specialized surface treatment applications also draw on its reducing chemistry.
Ammonia borane is supplied as a white crystalline powder, typically in research and specialty quantities reflecting its current stage of commercial development. It is available in technical and high-purity grades.
Purity specifications commonly range from 97% to 99%+ for laboratory and advanced materials applications. Packaging is generally offered under inert atmosphere conditions to preserve stability during storage and transit.
