Overview

Azanium perchlorate (CAS 7790-98-9) is an inorganic ammonium salt with strong oxidizing and explosive properties. This white crystalline compound, also known by its IUPAC name azanium perchlorate, represents a highly energetic material with the molecular formula ClH4NO4 and a molecular weight of 117.49 g/mol. The substance belongs to the perchlorate family of oxidizing agents and exhibits dual hazard characteristics as both an explosive material (Class 1.1) and a strong solid oxidizer (Class 1), requiring careful handling protocols and specialized storage conditions. The compound's structure consists of ammonium cations paired with perchlorate anions, creating a salt that demonstrates significant reactivity potential. Its classification under ADR transport regulations as Class 1 material reflects the serious safety considerations necessary when handling this substance. The presence of both GHS01 (exploding bomb) and GHS03 (flame over circle) pictograms emphasizes its explosive and oxidizing hazards, warranting the "Danger" signal word designation. In industrial applications, azanium perchlorate finds use primarily in specialized pyrotechnic formulations, propellant compositions, and as an oxidizing agent in specific chemical processes. The aerospace industry utilizes this compound in solid rocket propellants where controlled energy release is required. Unlike related energetic compounds such as 2,4,6-trinitro-N-(2,4,6-trinitrophenyl)aniline, azanium perchlorate offers different performance characteristics due to its inorganic nature and specific oxidizing properties. Due to its hazardous classification and regulatory requirements, this material requires specialized handling expertise and appropriate safety infrastructure. OYSI provides azanium perchlorate to qualified industrial customers with proper authorization and safety certifications for legitimate technical applications.

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 compound is classified as both an explosive (Expl. 1.1) and oxidizing solid (Ox. Sol. 1), making it a highly hazardous material that requires careful handling and storage under strict safety protocols.

What are the physicochemical properties of azanium perchlorate?

Azanium perchlorate is a white crystalline solid at room temperature with high water solubility typical of perchlorate compounds. As an oxidizing substance, it readily releases oxygen when heated or subjected to shock, contributing to its explosive nature. The compound is hygroscopic and can absorb moisture from air. Its dual classification as both explosive and oxidizing solid reflects its inherent instability and strong oxidizing potential under various conditions.

What is azanium perchlorate used for?

Azanium perchlorate is primarily used in specialized industrial applications requiring controlled explosive or oxidizing properties. Common applications include pyrotechnic compositions, solid rocket propellants, and specific chemical synthesis processes. Due to its dual hazard classification as both explosive and oxidizing solid, its use is typically restricted to professional settings with appropriate safety infrastructure and trained personnel capable of handling Class 1 dangerous goods.

How to handle azanium perchlorate safely?

Azanium perchlorate requires extreme safety precautions due to its explosive and oxidizing properties. Personnel must wear appropriate PPE including antistatic clothing, safety glasses, and protective gloves. Handle only in designated areas away from heat sources, friction, and incompatible materials. Use non-sparking tools and ensure proper grounding to prevent static electricity buildup. Work in well-ventilated areas and maintain emergency procedures for explosive materials readily accessible.

How to store azanium perchlorate correctly?

Azanium perchlorate must be stored in cool, dry conditions away from heat sources, incompatible materials, and ignition sources. Storage areas should comply with explosive materials regulations, featuring appropriate separation distances and fire protection systems. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from reducing agents, organic materials, and metals. Regular inspection of storage conditions and container integrity is essential for safety.

What to do in case of contact with azanium perchlorate?

Azanium perchlorate contact requires immediate action depending on exposure type. For skin contact, remove contaminated clothing and flush affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek urgent medical care. Always consult safety data sheets for specific first aid measures.

How to dispose of azanium perchlorate appropriately?

Azanium perchlorate disposal must comply with hazardous waste regulations for explosive and oxidizing materials. Contact licensed hazardous waste disposal companies specialized in explosive materials handling. Never attempt disposal through normal waste streams or sewerage systems. Small quantities may require neutralization or dilution procedures under professional supervision. Always consult local environmental authorities and follow specific waste classification codes for proper disposal documentation and tracking.

How to transport azanium perchlorate?

Azanium perchlorate is classified as Class 1 dangerous goods under ADR regulations for road transport. Transportation requires specialized explosive materials handling procedures, appropriate packaging, and proper documentation. Only certified carriers with explosive materials permits can transport this substance. Packaging must meet UN specifications for Class 1 materials, and vehicles must display appropriate hazard placards and carry emergency response information.

Is azanium perchlorate subject to specific regulations?

Azanium perchlorate is subject to extensive regulations under REACH, CLP, and explosive materials legislation. Its classification as Expl. 1.1 and Ox. Sol. 1 triggers specific requirements for registration, authorization, and restriction procedures. The compound requires proper hazard labeling with GHS01 and GHS03 pictograms and 'Danger' signal word. Industrial users must implement risk management measures and report usage under chemical safety regulations.
