Applications
CAS 86-55-5 is a versatile aromatic carboxylic acid intermediate widely used in organic synthesis, photosensitive materials, and polymer chemistry. In organic synthesis, it serves as a key building block for manufacturing naphthalene-based derivatives, including pharmaceuticals, dyes, and agrochemicals. In the photosensitive industry, it is a critical raw material for producing photoresists, printing plate films, and sensitizers for printed circuit boards (PCBs) and photographic developers. It also acts as a modifier for special resins, enhancing the heat resistance, chemical stability, and mechanical properties of coatings, adhesives, and engineering plastics. Additionally, it is used in research laboratories as a standard reference material for chromatographic analysis and as a ligand in coordination chemistry studies.
Safety Information
Classified as GHS07 (Xi, Irritant); hazard statements H315 (Skin Irritation), H319 (Eye Irritation), H335 (Respiratory Irritation).
- Inhalation: Dust irritates the respiratory tract; use a fume hood and dust mask.
- Skin Contact: May cause redness, itching, or mild irritation; wear nitrile gloves and wash with soap and water.
- Eye Contact: Causes severe irritation (tearing, pain); wear safety goggles and rinse eyes with water for ≥15 minutes.
- Ingestion: Low acute toxicity (LD50 oral rat >5,000 mg/kg); do not induce vomiting and seek medical attention.
- Chemical Hazards: Stable under normal conditions; avoid strong oxidants, strong bases, and high temperatures (>200 °C) (risk of decomposition to toxic naphthalene fumes).
- Storage: Store in a cool, dry, well-ventilated area; keep containers tightly closed and separate from incompatible substances.
- Disposal: Dispose of as hazardous waste in accordance with local regulations; incinerate in an approved facility.
