Overview

2-nitrooxyethyl nitrate (CAS 628-96-6) is a highly energetic nitrate ester compound characterized by extreme instability and acute toxicity properties. This dual nitrate ester compound, with the molecular formula C2H4N2O6, represents one of the most hazardous chemicals in the explosive materials category. The molecule contains two nitrate groups attached to an ethylene backbone, creating a structure that is inherently unstable and prone to explosive decomposition. With a molecular weight of 152.06 g/mol, this compound exhibits properties typical of energetic materials while presenting significant handling challenges due to its classification as an unstable explosive. The safety profile of 2-nitrooxyethyl nitrate demands extreme caution, as evidenced by its multiple GHS pictograms including explosion (GHS01), skull and crossbones (GHS06), and health hazard (GHS08). The compound carries acute toxicity classifications ranging from Category 1 to Category 2, indicating potentially fatal exposure risks through multiple routes. Additionally, its STOT RE 2 classification suggests repeated exposure may cause organ damage, making proper protective equipment and handling procedures absolutely essential. Industrial applications of this compound are highly specialized and limited to controlled environments where its energetic properties can be safely utilized. Primary uses include propellant formulations and specialized explosive applications where high energy density is required. The compound shares certain characteristics with other energetic materials such as 2-methyl-1,3,5-trinitrobenzene, though each exhibits distinct stability and performance profiles. OYSI maintains strict protocols for handling such high-hazard materials and can provide technical consultation regarding safe handling procedures and regulatory compliance for qualified industrial customers requiring this specialized compound.

Frequently Asked Questions

What is 2-nitrooxyethyl nitrate?

2-nitrooxyethyl nitrate is a highly dangerous explosive compound with the molecular formula C2H4N2O6 and CAS number 628-96-6. This chemical substance belongs to the class of organic nitrates and has a molecular weight of 152.06 g/mol. It is classified as an unstable explosive with severe acute toxicity properties, making it extremely hazardous to handle and requiring specialized safety protocols in any industrial or research application.

What are the physicochemical properties of 2-nitrooxyethyl nitrate?

2-nitrooxyethyl nitrate is a nitrate ester compound with a molecular formula of C2H4N2O6 and molecular weight of 152.06 g/mol. As an organic nitrate, it typically exists as a liquid or crystalline solid at room temperature. The compound is highly unstable and sensitive to heat, friction, and impact due to its explosive nature. Its specific physical properties including melting point, boiling point, and solubility require careful laboratory determination under controlled conditions.

What is 2-nitrooxyethyl nitrate used for?

2-nitrooxyethyl nitrate is primarily used in specialized research applications and potentially in explosive formulations due to its unstable explosive classification. Given its extreme toxicity and explosive properties, its applications are highly restricted and typically limited to controlled laboratory environments or specific industrial processes requiring explosive compounds. Any use requires strict regulatory compliance and specialized handling procedures due to its dangerous characteristics and acute toxicity profile.

How to handle 2-nitrooxyethyl nitrate safely?

2-nitrooxyethyl nitrate requires extreme safety precautions due to its unstable explosive and acute toxic properties. Personnel must wear full protective equipment including chemical-resistant gloves, protective clothing, and respiratory protection. Work must be conducted in specialized facilities with explosion-proof equipment, proper ventilation, and emergency procedures in place. Only trained professionals should handle this substance, following strict protocols to prevent exposure, ignition, or shock that could trigger explosive decomposition.

How to store 2-nitrooxyethyl nitrate correctly?

2-nitrooxyethyl nitrate must be stored in specialized explosive storage facilities with temperature control and shock-resistant containers. Storage areas require proper ventilation, fire suppression systems, and separation from incompatible materials including oxidizers, reducing agents, and heat sources. Quantities should be minimized, and storage must comply with local explosive storage regulations. Regular inspection and monitoring are essential due to the compound's unstable nature and potential for spontaneous decomposition.

What to do in case of contact with 2-nitrooxyethyl nitrate?

Immediate medical attention is required for any contact with 2-nitrooxyethyl nitrate due to its extreme acute toxicity. For skin contact, remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes.
