Overview
Azanium perchlorate (CAS 7790-98-9) is an inorganic ammonium salt with powerful oxidizing and explosive properties. This crystalline compound, also known by its IUPAC name azanium perchlorate, represents a significant chemical in the explosives and propellant industry. With the molecular formula ClH4NO4 and a molecular weight of 117.49 g/mol, azanium perchlorate exhibits dual hazardous characteristics as both a Class 1.1 explosive and a Category 1 oxidizing solid. The compound's EC number 232-235-1 identifies it within European chemical regulations, where it requires careful handling protocols due to its inherent instability and reactive nature. The substance displays exceptional oxidizing capabilities, making it particularly valuable in pyrotechnic formulations and solid rocket propellants. Its ability to release oxygen rapidly during decomposition provides the necessary oxidizing environment for sustained combustion reactions. Safety considerations are paramount when handling azanium perchlorate, as indicated by the GHS01 and GHS03 pictograms denoting explosive and oxidizing hazards respectively. The "Danger" signal word emphasizes the critical importance of proper storage, transportation, and handling procedures under ADR Class 1 regulations. Industrial applications primarily focus on aerospace propulsion systems, where azanium perchlorate serves as an oxidizer in composite solid propellants. The compound also finds use in specialized pyrotechnic compositions and research applications requiring controlled oxidation reactions. Unlike more complex explosive compounds such as 2,4,6-trinitro-N-(2,4,6-trinitrophenyl)aniline, azanium perchlorate offers simpler handling characteristics while maintaining high performance oxidizing properties. OYSI provides azanium perchlorate to qualified industrial customers with appropriate safety certifications and handling capabilities throughout Europe.

Frequently Asked Questions
What is azanium perchlorate?
Azanium perchlorate is an inorganic chemical compound with the molecular formula ClH4NO4 and CAS number 7790-98-9. It has a molecular weight of 117.49 g/mol and belongs to the class of perchlorate salts. This substance is classified as both an explosive (Expl. 1.1) and a strong oxidizing solid (Ox. Sol. 1), making it a highly hazardous material that requires careful handling and storage under controlled conditions.
What are the physicochemical properties of azanium perchlorate?
Azanium perchlorate is typically a white crystalline solid at room temperature with high solubility in water. As a perchlorate compound, it exhibits strong oxidizing properties and is highly reactive with organic materials and reducing agents. The substance is hygroscopic, meaning it readily absorbs moisture from air. Its crystalline structure and ionic nature contribute to its explosive characteristics when subjected to shock, friction, or heat.
What is azanium perchlorate used for?
Azanium perchlorate is primarily used in pyrotechnic applications, explosive formulations, and as an oxidizing agent in specialized chemical processes. Its strong oxidizing properties make it valuable in rocket propellants and military applications. The compound is also utilized in analytical chemistry for specific oxidation reactions and in research applications where controlled explosive or oxidizing properties are required under strict safety protocols.
How to handle azanium perchlorate safely?
Azanium perchlorate requires extreme safety precautions due to its explosive and oxidizing nature. Personnel must wear appropriate PPE including safety goggles, protective clothing, and work in well-ventilated areas away from heat sources and incompatible materials. Avoid friction, shock, and static electricity. Use non-sparking tools and ensure proper grounding. Only trained professionals should handle this substance, and emergency procedures must be readily available.
How to store azanium perchlorate correctly?
Azanium perchlorate must be stored in cool, dry conditions away from heat, ignition sources, and incompatible materials such as organic compounds, metals, and reducing agents. Use appropriate explosive-rated storage facilities with proper ventilation and temperature control. Store in original containers, properly labeled, and separate from other chemicals. Access should be restricted to authorized personnel only, with proper inventory tracking and security measures in place.
What to do in case of contact with azanium perchlorate?
In case of skin contact with azanium perchlorate, immediately remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. For eye contact, flush with clean water and seek immediate medical attention. If inhaled, move to fresh air and monitor breathing. In case of ingestion, do not induce vomiting and seek immediate medical care. Always inform medical personnel about the specific substance involved.
How to dispose of azanium perchlorate appropriately?
Azanium perchlorate disposal requires specialized hazardous waste procedures due to its explosive classification. Contact licensed hazardous waste disposal companies experienced in handling explosive materials. Never dispose of through regular waste streams or attempt neutralization without proper expertise. Small quantities may require detonation or controlled burning by qualified professionals. Always follow local and national regulations for explosive waste disposal and maintain proper documentation.
How to transport azanium perchlorate?
Azanium perchlorate is classified as ADR Class 1 dangerous goods, requiring specialized transportation procedures for explosive materials. Transport must comply with international dangerous goods regulations, using appropriate packaging, labeling, and documentation. Only certified carriers with explosive transport permits can handle shipment. Vehicles must meet specific safety requirements, and transport routes may be restricted. Proper emergency response information must accompany all shipments.
Is azanium perchlorate subject to specific regulations?
Azanium perchlorate is subject to extensive regulations including REACH registration requirements, CLP classification as explosive and oxidizing, and specific controls under explosive legislation. Its dual classification requires compliance with both explosive handling regulations and chemical safety standards. Import/export may require special permits, and use is typically restricted to licensed facilities. Regular safety assessments and risk management measures are mandatory for commercial handling.
