Introduction
3,3′-Dichlorobenzidine Hydrochloride
Chemical Formula: C₁₂H₁₀Cl₂N₂·HCl
Structure: Chlorinated aromatic diamine with:
- Two benzene rings substituted with chlorine atoms at the 3-positions.
- A benzidine group (-NH-NH-) linking the rings.
- A hydrochloride salt attached to one amino group.
Physical Properties
- Appearance: Gray to white crystalline solid.
Applications
- Dye & Pigment Production:
- Key intermediate for textile dyes, plastics, and printing inks.
- Polymer Synthesis:
- Used in producing specialty polymers.
- Organic Chemistry:
- Reagent for synthesizing nitrogen-containing compounds.
Safety Considerations ⚠️
- Toxicity:
- Potential carcinogen; toxic via inhalation, ingestion, or skin contact.
- Handling:
- Use PPE (gloves, goggles, respirator) and ensure adequate ventilation.
- Storage:
- Store in a cool, dry, airtight container away from moisture and incompatible substances.
Summary:
3,3′-Dichlorobenzidine hydrochloride’s role as a dye/pigment intermediate is critical in industrial chemistry. Its carcinogenic risk mandates strict adherence to safety protocols during handling and storage.
