3-Ethynylaniline Hydrochloride CAS 207226-02-6

1. 3-Ethynylaniline hydrochloride is primarily used as a key building block in click chemistry and other Cu-catalyzed azide-alkyne cycloaddition reactions for pharmaceutical and materials science applications.
2. 3-Ethynylaniline Hydrochloride CAS 207226-02-6 serves as a versatile intermediate for synthesizing functionalized anilines, heterocycles, and conjugated polymers or molecular wires.
3. This compound is also utilized in the development of bioactive probes, sensors, and advanced organic materials.

1. Store 3-ethynylaniline hydrochloride in a cool, dry, well-ventilated place, under an inert atmosphere if possible, and protected from light and moisture.
2. Keep the container tightly closed and clearly labeled. Separate from strong oxidizing agents, strong bases, and sources of heat or ignition.
3. Handle with appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles, and a lab coat. Use a fume hood to avoid inhalation of dust, as 3-Ethynylaniline Hydrochloride CAS 207226-02-6 is an aromatic amine salt.

1. Isolate the spill area, ensure ventilation, and wear suitable protective equipment (gloves, goggles, protective clothing, dust mask/respirator).
2. Carefully 3-Ethynylaniline Hydrochloride CAS 207226-02-6 collect the spilled solid with a clean, non-sparking tool. Avoid creating dust. Place the contaminated material in a sealed, labeled container for hazardous waste disposal.
3. Prevent the material from entering drains, sewers, or the environment. Clean the affected surface thoroughly with water and detergent, collecting washings for proper disposal.

1. 3-Ethynylaniline hydrochloride is harmful if swallowed, inhaled as dust, or in contact with skin. It is an aromatic amine hydrochloride, causing skin and eye irritation, and may cause respiratory sensitization or organ damage.
2. 3-Ethynylaniline Hydrochloride CAS 207226-02-6 is combustible and may emit toxic fumes (hydrogen chloride, nitrogen oxides, carbon oxides) when heated to decomposition.
3. Always consult the official 3-ethynylaniline hydrochloride Safety Data Sheet (SDS) for comprehensive hazard, handling, and regulatory information. Handle as a toxic and potentially sensitizing compound.
