7-Anilino-3-diethylamino-6-methyl Fluoran /ODB-1 CAS 29512-49-0

1. 7-Anilino-3-diethylamino-6-methyl fluoran is a heat-sensitive thermochromic pigment used as a "shutter" material in smart fibers and coatings, where its molecular structure reversibly blocks or transmits light in response to temperature changes .
2. ODB-1 CAS 29512-49-0 functions as a pH indicator and fluorescent dye, undergoing reversible protonation and deprotonation that allows visualization and quantification of pH changes in cellular and subcellular environments .
3. 7-Anilino-3-diethylamino-6-methyl fluoran serves as a key intermediate in the synthesis of organic light-emitting diodes (OLEDs) and photonic devices, leveraging its high photostability and tunable luminescent properties .
4. Researchers utilize 7-anilino-3-diethylamino-6-methyl fluoran in biomedical applications, including drug delivery systems and photodynamic therapy, where its diethylamino group enhances solubility and cellular uptake .

1. 7-Anilino-3-diethylamino-6-methyl fluoran must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, with recommended storage at 2-8°C (refrigerated) .
2. The product should be kept away from incompatible materials such as strong oxidizing agents and stored separately from foodstuff containers to prevent contamination .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling 7-anilino-3-diethylamino-6-methyl fluoran, as ODB-1 CAS 29512-49-0 is harmful by inhalation, in contact with skin, and if swallowed .
4. Avoid formation of dust and aerosols, ensure adequate ventilation in work areas (preferably a chemical fume hood), 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 7-anilino-3-diethylamino-6-methyl fluoran is released .
2. Collect ODB-1 CAS 29512-49-0 by sweeping or vacuuming without creating dust using non-sparking tools, or mix with inert absorbent materials such as sand or diatomite, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent 7-anilino-3-diethylamino-6-methyl fluoran 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 with flue gas scrubbing .

1. 7-Anilino-3-diethylamino-6-methyl fluoran is not classified as highly flammable but may decompose under fire conditions, with a flash point of approximately 361°C .
2. Use dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires involving the product; do NOT use a direct water jet as ODB-1 CAS 29512-49-0 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 7-anilino-3-diethylamino-6-methyl fluoran due to hazardous decomposition gases .
4. Hazardous decomposition products formed under fire conditions include toxic fumes of carbon monoxide and nitrogen oxides (NOx); contain fire runoff to prevent environmental contamination .
