Applications
CAS 3964-18-9 (2,3-Dimethyl-2,3-dinitrobutane) is an important organic nitro compound with unique chemical properties, mainly used in the field of explosive detection, and also has certain applications in organic synthesis[1]. Its core application is as an explosive detection reagent, which can effectively detect plastic explosives with a content of 1%, and has high sensitivity and specificity, making it widely used in security inspection scenarios such as airports, stations, and customs[1]. It can react specifically with plastic explosives to produce obvious characteristic signals, which is convenient for rapid detection and identification of explosives, providing an important guarantee for public safety. In the field of organic synthesis, it can be used as a nitro-containing intermediate to participate in the synthesis of complex organic molecules, and the nitro groups in its structure can undergo reduction, substitution and other reactions, providing flexible structural modification sites for the synthesis of target compounds. In addition, it can be used as a standard substance in analytical testing, used for qualitative and quantitative detection of nitro compounds in environmental samples and industrial products, ensuring the accuracy and reliability of detection results. It also has potential application value in the research of chemical reaction mechanisms, especially in the research of nitro group reaction characteristics and alkane derivative synthesis reactions, providing a basis for the innovation and optimization of chemical synthesis technology.
Safety Information
- Hazard Category: Toxic substance (GHS hazard symbol: GHS06; hazard statements: H300); acute oral toxicity (Category 2); dangerous goods transportation code: UN 2811 6.1/PG 2; hazard code: R25; dangerous goods label: T[1][7]
- Hazards: Acute oral toxicity, swallowing is life-threatening[7]; it is slightly irritating to the skin and eyes; direct skin contact may cause slight redness and itching, and long-term contact may lead to skin dryness; eye contact may cause conjunctival hyperemia and burning sensation. Inhalation of dust may cause respiratory tract discomfort such as cough and chest tightness. There is no obvious chronic toxicity, but long-term large-scale contact may cause potential harm to the body[1][7].
- Operation Precautions: All operations shall be carried out in a well-ventilated environment; operators shall wear nitrile gloves, protective clothing, safety goggles and dust mask to avoid direct contact, inhalation of dust and accidental ingestion[7]. Do not eat, drink or smoke during operation; clean the face and hands thoroughly after operation. The operation area shall be equipped with emergency rescue equipment and first aid drugs; avoid contact with oxidants to prevent chemical reactions. It is only used for research and development and industrial purposes, and shall not be used for pharmaceuticals, household products and other purposes[7].
- Storage & Transportation Requirements: It shall be stored in a sealed HDPE barrel or cardboard barrel (lined with plastic bag); stored in a cool, dry and well-ventilated place at room temperature, protected from light and moisture; locked and stored, and only accessible to qualified or authorized personnel[7]. Transportation shall avoid violent vibration, sun exposure and moisture; it shall be transported in accordance with the regulations of Class 6.1 dangerous goods, and shall not be mixed with food, feed, oxidants and acids[1][7]. Common packaging specifications include 10g, 100g, 1kg, 25kg, which can meet the needs of laboratory, small-scale production and industrial application[3].
- Waste Disposal: Waste residues and contaminated packaging shall be disposed of in strict accordance with the management regulations of hazardous chemicals, and shall not be directly discharged into water bodies, soil or sewers to avoid environmental pollution[7]. The waste shall be collected and treated by professional hazardous waste disposal institutions in accordance with relevant regulations; when disposing, it shall be properly contained to prevent leakage[7].
- First Aid Measures: In case of skin contact, immediately take off contaminated clothes, rinse thoroughly with plenty of soapy water and clean water for at least 15 minutes, and seek medical advice if there is discomfort; in case of eye contact, rinse with plenty of water for at least 15 minutes (take off contact lenses if worn) and seek medical advice in time; in case of accidental ingestion, do not induce vomiting (only induce vomiting if the patient is fully conscious and cannot receive medical treatment within 1 hour), give 1-2 cups of warm water, and seek medical treatment immediately with the product label[7]; in case of inhalation discomfort, move to a well-ventilated place, rest and keep warm, and seek medical advice if symptoms persist.
- Safety Instructions: S45 (In case of accident or feeling unwell, seek medical advice immediately (preferably with the product container label)); WGK Germany: 3; TSCA: Yes
