SHORT DESCRIPTION

Anilinium Chloride Extra Pure is a high-purity, white to off-white crystalline salt formed from aniline and hydrochloric acid, commonly used in laboratory chemistry for organic synthesis and analytical applications. It serves as a stable, water-soluble source of the anilinium ion, useful in studies of aromatic amines, protonation reactions, and acid-base equilibria. In synthetic chemistry, it acts as an intermediate in the preparation of dyes, pharmaceuticals, and polymer additives. The extra pure grade ensures minimal impurities, making it suitable for sensitive experimental procedures requiring high precision. It should be stored in a tightly sealed container in a cool, dry place to maintain stability and prevent degradation.

Precursor for Aniline Regeneration
- Easily converted back to aniline (C₆H₅NH₂) via base treatment, useful in stepwise syntheses where temporary protonation is needed.
Demonstration of Aromatic Ammonium Salt Properties
- Ideal for educational labs illustrating protonation of amines, hydrogen bonding, and infrared/NMR spectral changes upon salt formation.
Model Compound in Organic Mechanistic Studies
- Studied for its role in protonation equilibria, electrophilic aromatic substitution, and reaction kinetics in undergraduate and research labs.

Secondary Uses

Starting Material for Anilinium-Based Ionic Liquids
- Occasionally used in research to prepare low-melting salts or ionic liquids for green chemistry and electrochemical studies.
Reagent in Electrochemical and Conductivity Studies
- Useful for studying the conductivity of substituted ammonium salts in various solvents.
Teaching Crystallization and Salt Characterization
- A stable, crystalline compound that demonstrates melting point determination, recrystallization, and elemental analysis.
Source of Weak Acid Cation in Ion Exchange Research
- Studied in ion exchange systems or chromatographic methods for separating aromatic amines.
Control Compound in Aromatic Substitution Pathway Experiments

Used to observe the effect of protonation on nucleophilic and electrophilic behavior in substituted benzenes.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):
- Wear a lab coat, chemical-resistant gloves (nitrile or neoprene), and safety goggles.
- Use in a fume hood to prevent inhalation of vapors or dust.
Handling:
- Avoid inhalation, ingestion, and contact with skin or eyes.
- Prevent formation of dust and avoid exposure to heat, light, and strong oxidizers.
- Ensure containers are kept tightly closed and handled with non-sparking tools.
Storage:
- Store in a cool, dry, and well-ventilated area.
- Keep container tightly sealed and protected from light and moisture.
- Store away from oxidizing agents, acids, and strong bases.
Hygiene Measures:
- Wash hands thoroughly after handling.
- Do not eat, drink, or smoke in the lab.
- Decontaminate equipment and surfaces after use.

FIRST AID MEASURES

Inhalation:
- Move person to fresh air immediately.
- If breathing is difficult, administer oxygen.
- Seek immediate medical attention—may cause respiratory tract irritation or CNS effects (like dizziness or headache).
Skin Contact:
- Rinse skin with plenty of soap and water.
- Remove contaminated clothing and wash before reuse.
- Seek medical advice—aniline derivatives can be absorbed through skin and affect blood oxygenation.
Eye Contact:
- Rinse cautiously with plenty of water for at least 15 minutes.
- Hold eyelids apart and remove contact lenses if present.
- Seek immediate medical attention—may cause corneal irritation.
Ingestion:
- Rinse mouth thoroughly.
- Do not induce vomiting.
- Give water to dilute if the person is conscious.
- Seek immediate medical attention—anilinium compounds can cause methemoglobinemia, leading to oxygen transport issues.

FIRE FIGHTING MEASURES

Suitable Extinguishing Media:
- Use dry chemicals, CO₂, alcohol-resistant foam, or water spray.
Specific Hazards:
- Not highly flammable, but upon heating or fire may release:
  - Toxic fumes of nitrogen oxides (NOₓ)
  - Hydrogen chloride (HCl)
  - Aniline vapors
Protective Equipment for Firefighters:
- Wear self-contained breathing apparatus (SCBA) and full protective gear.
Firefighting Instructions:
- Use water spray to cool exposed containers.
