2-(4-Methylphenyl)propanoic Acid CAS 938-94-3

1. 2-(4-Methylphenyl)propanoic acid is a key intermediate in the synthesis of a variety of biologically active compounds, including pharmaceuticals and agrochemicals .
2. 2-(4-Methylphenyl)propanoic acid CAS 938-94-3 is primarily used as a building block in organic synthesis for the production of nonsteroidal anti-inflammatory drugs (NSAIDs) such as Ibuprofen, as the molecule represents the core 2-arylpropanoic acid structure of the profen class .
3. The compound serves as a valuable substrate in the study of enzymatic and chiral resolution processes, as the biological activity of profens is typically enantioselective (S-enantiomer) .
4. Researchers utilize this product as a laboratory reagent in stereoselective synthesis, including enantioselective hydrogenation and arylation reactions, and as a reference standard for analytical method development .

1. 2-(4-Methylphenyl)propanoic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture .
2. 2-(4-Methylphenyl)propanoic acid CAS 938-94-3 is classified with 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 to prevent decomposition; 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 2-(4-Methylphenyl)propanoic acid is released .
2. Collect 2-(4-Methylphenyl)propanoic acid CAS 938-94-3 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 as discharge into the environment must be avoided .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. 2-(4-Methylphenyl)propanoic acid is combustible with a flash point of approximately 190.8°C, and under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide and carbon dioxide .
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 2-(4-Methylphenyl)propanoic acid CAS 938-94-3 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 2-(4-Methylphenyl)propanoic 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 .
