Trihydroxymethyl aminomethane, abbreviated as Tris, is a buffer widely used in biochemical and molecular biology experiments. It plays an important role in experiments such as protein electrophoresis, nucleic acid electrophoresis, and cell culture. However, when using trimethylaminomethane, researchers need to understand its safety information in order to use and handle it correctly in laboratory environments. The following will provide a detailed introduction to the safety information of trimethylolaminomethane in the form of a safety data sheet, including physical properties, hazard assessment, emergency measures, and other aspects.
1. Appearance and odor
Appearance: White crystalline or crystalline powder
Odor: odorless and tasteless
2. Molecular structure
The molecular structure of trimethylaminomethane is formed by the combination of three amino groups and one hydroxyl (OH) group. Its molecular formula is C3H11NO3, with a molecular weight of 121.135, and the resulting molecule has good buffering performance. The melting point range of trimethylaminomethane is 168-172 ℃, the boiling point range is 219-220 ℃ (1mmHg), and the density is 1.479g/mL (20 ℃).
Trihydroxymethyl aminomethane powder
Trihydroxymethylaminomethane has lower acute toxicity to the human body under general usage conditions, but direct contact with skin, eyes, and respiratory tract should still be avoided.
2. Nature of fire and explosion:
Fire: Trihydroxymethylaminomethane is a combustible substance that may ignite when exposed to open flames.
Explosive: Trihydroxymethylaminomethane itself is not explosive, but it may release harmful gases when decomposed at high temperatures.
3. Potential health hazards
Inhalation: Long term inhalation of dust from trimethylaminomethane may cause respiratory irritation, and it is recommended to use in a well ventilated environment.
Eye contact: Trihydroxymethylaminomethane entering the eyes may cause pain and redness, and should be immediately rinsed with plenty of water for at least 15 minutes after contact.
Ingestion: Misingestion of trimethylaminomethane may cause discomfort. If any abnormalities occur, seek medical attention promptly.
4. Environmental impact
Trihydroxymethylaminomethane has a certain impact on aquatic ecosystems, so it is necessary to comply with environmental regulations during use and treatment to prevent pollution to the environment.
1. Personal protection
Respiratory protection: During operation, use appropriate dust masks to ensure that the respiratory tract is not affected by dust.
Skin protection: Wear protective gloves and goggles to avoid direct contact between trimethylaminomethane and the skin, in order to reduce potential risks.
Other: Wear appropriate laboratory clothing to protect the entire body.
2. Operational measures
Operating environment: Operate in a well ventilated laboratory environment to avoid prolonged exposure to trimethylaminomethane dust.
Operation precautions: Avoid contact between trimethylaminomethane and strong oxidants and acidic substances to prevent unnecessary reactions.
Waste disposal: Properly classify waste according to relevant regulations and hand it over to professional institutions for disposal.
3. Emergency measures
Eye contact: If trimethylaminomethane solution or dust is accidentally splashed into the eyes, immediately rinse with plenty of water for at least 15 minutes, and seek medical help.
Inhalation: If inhaling trimethylaminomethane dust, immediately transfer to fresh air and provide respiratory first aid if necessary.
Ingestion: After ingesting trimethylaminomethane, one should immediately drink a large amount of water to avoid inducing vomiting, and seek medical assistance.
1. Laboratory operating procedures: In laboratory operations, researchers must follow the laboratory operating procedures and strictly follow them to avoid accidents caused by operational errors.
2. Regular training: Laboratory personnel should receive relevant safety training to understand the properties, usage methods, and accident handling of trimethylaminomethane, and improve their understanding of potential risks.
3. First aid equipment preparation: The laboratory should be equipped with sufficient first aid equipment, including eye washers, emergency shower facilities, etc., to provide timely first aid measures in emergency situations.
