9-Acridinecarboxylic Acid CAS 5336-90-3

1. 9-Acridinecarboxylic acid is a heterocyclic building block primarily used in the synthesis of acridine-based pharmaceuticals, particularly as an intermediate for preparing compounds with potential anticancer, antimicrobial, and antiviral activities .
2. 9-Acridinecarboxylic Acid CAS 5336-90-3 serves as a fluorescent probe and analytical reagent for studying nucleic acid interactions, given the acridine core's ability to intercalate into DNA and RNA .
3. 9-Acridinecarboxylic acid is employed in research as a scaffold for developing photosensitizers in photodynamic therapy (PDT) and as a component in fluorescent dyes for biological imaging .
4. Researchers utilize 9-Acridinecarboxylic Acid CAS 5336-90-3 in supramolecular chemistry for constructing metal-organic frameworks (MOFs) and coordination complexes with lanthanides, leveraging its carboxylate group for metal binding .

1. 9-Acridinecarboxylic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light, with recommended storage at 0-8°C (refrigerated) .
2. 9-Acridinecarboxylic Acid CAS 5336-90-3 is classified with GHS hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong oxidizing agents; avoid formation of dust and aerosols, and wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when 9-Acridinecarboxylic acid is released .
2. Collect 9-Acridinecarboxylic Acid CAS 5336-90-3 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. 9-Acridinecarboxylic acid is combustible and may decompose under fire conditions, with a flash point of 194.8°C; hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as 9-Acridinecarboxylic Acid CAS 5336-90-3 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 9-Acridinecarboxylic acid due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination .
