2,2-dimethylpropan-1-ol

2,2-dimethylpropan-1-ol is a branched primary alcohol with the molecular formula C5H12O and CAS number 75-84-3. Also known as neopentyl alcohol, this compound features a highly branched structure with two methyl groups attached to the second carbon atom. With a molecular weight of 88.15 g/mol, it belongs to the family of aliphatic alcohols and is classified as a flammable liquid with moderate toxicity properties.

2,2-dimethylpropan-1-ol is a colorless liquid at room temperature with a characteristic alcohol odor. Due to its branched structure, it exhibits unique physical properties compared to linear alcohols of similar molecular weight. The compound is moderately soluble in water due to its hydroxyl group and miscible with most organic solvents. Its highly branched structure affects its boiling point and viscosity, making it distinct from other pentanol isomers.

2,2-dimethylpropan-1-ol is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. Its unique branched structure makes it valuable for producing specialty esters, ethers, and other derivatives. The compound serves as a building block in the synthesis of plasticizers, surfactants, and pharmaceutical compounds. Additionally, it finds applications in research laboratories as a reagent and in the production of fine chemicals where its specific molecular structure is required.

2,2-dimethylpropan-1-ol must be handled with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume hoods to prevent inhalation exposure. Keep away from ignition sources, heat, and flames as it is classified as Flam. Liq. 3. Avoid skin and eye contact due to its Acute Tox. 4 classification. Use non-sparking tools and ensure proper grounding of equipment during handling.

2,2-dimethylpropan-1-ol should be stored in a cool, dry, well-ventilated area away from heat sources and ignition points. Use appropriate containers made of compatible materials and ensure proper labeling with GHS02 and GHS07 pictograms. Store separately from strong oxidizing agents and incompatible materials. Maintain storage temperatures below flash point and ensure containers are tightly sealed to prevent vapor release. Implement proper fire prevention measures in storage areas.

In case of skin contact with 2,2-dimethylpropan-1-ol, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of clean water for 15-20 minutes and seek medical attention. If inhaled, move person to fresh air and seek medical advice if respiratory irritation occurs. In case of ingestion, do not induce vomiting and seek immediate medical attention.

2,2-dimethylpropan-1-ol must be disposed of according to local, regional, and national waste regulations as a hazardous chemical waste. Contact licensed waste disposal companies for proper treatment and disposal. Do not pour down drains or release into the environment. Small quantities may be suitable for controlled incineration at licensed facilities. Ensure proper classification as flammable waste and follow all applicable waste codes and transport requirements for hazardous waste disposal.

2,2-dimethylpropan-1-ol is classified under ADR as Class 4.1 (Flammable solids), Packing Group II, indicating moderate danger level for transport. Packages must comply with appropriate packing instructions and be properly labeled with hazard labels and UN identification numbers. Use approved containers and ensure proper documentation including transport documents and emergency response information. Transport vehicles must meet ADR requirements for Class 4.1 substances and drivers need appropriate training.

2,2-dimethylpropan-1-ol is subject to REACH regulation requiring registration for manufacture or import above one tonne per year in the EU. The substance is classified under CLP regulation with specific hazard classes (Flam. Liq. 3, Acute Tox. 4, STOT SE 3) requiring appropriate labeling and safety data sheets. It is not currently listed as a SVHC substance. Users must comply with occupational health and safety regulations and environmental protection requirements in their respective jurisdictions.
