1-chloro-1,2-difluoroethane

1-chloro-1,2-difluoroethane is a halogenated organic compound with the molecular formula C2H3ClF2 and CAS number 338-64-7. This chemical belongs to the family of chlorofluorocarbons (CFCs) and has a molecular weight of 100.49 g/mol. It contains one chlorine atom and two fluorine atoms attached to an ethane backbone, making it a mixed halogenated hydrocarbon with specific industrial applications.

1-chloro-1,2-difluoroethane is typically a colorless gas or volatile liquid at room temperature, depending on pressure conditions. As a halogenated compound, it exhibits low solubility in water but good solubility in organic solvents. The presence of chlorine and fluorine atoms gives it distinctive chemical stability and low reactivity under normal conditions, with properties characteristic of fluorinated hydrocarbons.

1-chloro-1,2-difluoroethane is primarily used as an intermediate in chemical synthesis and as a specialty solvent in industrial applications. It serves as a building block for producing other fluorinated compounds and may be utilized in specific cleaning applications where its unique solvent properties are beneficial. The compound finds use in pharmaceutical and chemical manufacturing processes requiring controlled halogenated environments.

1-chloro-1,2-difluoroethane should be handled in well-ventilated areas or under fume extraction systems to prevent vapor accumulation. Personnel should wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Despite having no specific GHS classification, standard chemical handling precautions apply, including avoiding ignition sources and ensuring proper grounding of equipment to prevent static discharge during transfer operations.

1-chloro-1,2-difluoroethane should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage areas must be equipped with appropriate ventilation systems and spill containment measures. The chemical should be kept away from incompatible materials such as strong oxidizers, alkali metals, and reactive metals that could potentially react with halogenated compounds.

In case of skin contact with 1-chloro-1,2-difluoroethane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If vapors are inhaled, move the person to fresh air immediately and seek medical attention if breathing difficulties occur. For eye contact, flush with clean water for at least 15 minutes and consult medical personnel. Always seek professional medical advice for any exposure incidents.

1-chloro-1,2-difluoroethane must be disposed of according to local, national, and European waste regulations as a halogenated organic waste. The compound should never be released to the environment or disposed of through regular waste streams. Disposal must be carried out by licensed waste management companies capable of handling halogenated compounds through appropriate incineration or specialized treatment methods that prevent environmental contamination.

1-chloro-1,2-difluoroethane is classified under ADR Class 2 for transportation, indicating it is considered a compressed gas or gas-related material. Transportation must comply with ADR regulations for Class 2 substances, requiring appropriate packaging, labeling, and documentation. Vehicles must be properly equipped and drivers must hold valid ADR certifications for Class 2 materials. Proper shipping papers and emergency response information must accompany all shipments.

1-chloro-1,2-difluoroethane is subject to standard European chemical regulations under REACH and CLP frameworks, requiring registration and compliance with substance identification requirements. The compound is not classified as a Substance of Very High Concern (SVHC) and currently has no specific GHS hazard classification. However, it must comply with general chemical safety regulations, workplace exposure limits, and environmental protection measures applicable to halogenated organic compounds.
