4-Ethoxybenzaldehyde CAS 10031-82-0

1. 4-Ethoxybenzaldehyde CAS 10031-82-0 is widely used as a key intermediate in the production of fine chemicals, including fragrances and flavoring agents, where it imparts a sweet, floral, and anise-like odor . 4-Ethoxybenzaldehyde is approved as a flavoring substance by the FDA (FEMA 2413) and the European Union .
2. 4-Ethoxybenzaldehyde plays a significant role in pharmaceutical development, serving as a building block for active pharmaceutical ingredients and as a precursor in the synthesis of compounds with potential anti-inflammatory effects .
3. Applications of 4-Ethoxybenzaldehyde also include its use as a building block in organic synthesis, a reagent in polymer chemistry for modifying material properties, and as an analytical standard for the accurate quantification of related compounds .

1. Store 4-Ethoxybenzaldehyde CAS 10031-82-0 in a tightly sealed container under an inert gas in a cool, dry, and well-ventilated place, protected from light, as 4-Ethoxybenzaldehyde is air and light sensitive . Recommended storage temperatures vary from 2-8°C (refrigerated) to a cool, dark place below 15°C .
2. Keep 4-Ethoxybenzaldehyde strictly away from strong oxidizing agents and strong bases, as it is incompatible with these materials . Containers should be kept closed when not in use.
3. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves (nitrile recommended), safety goggles with side-shields, and protective clothing to avoid skin and eye contact, and inhalation of vapors or dust . Use only with adequate ventilation or in a fume hood.

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure adequate ventilation. Contain 4-Ethoxybenzaldehyde CAS 10031-82-0 using dry, inert, non-combustible absorbent material and prevent entry into drains or waterways .
2. Carefully collect 4-Ethoxybenzaldehyde material using non-sparking tools into sealed, labeled chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE, including chemical-resistant gloves and eye protection, during cleanup . 4-Ethoxybenzaldehyde is a combustible liquid; use alcohol-resistant foam, dry chemical, or carbon dioxide to extinguish fires, and wear self-contained breathing apparatus (SCBA) .

1. 4-Ethoxybenzaldehyde CAS 10031-82-0 is classified with GHS signal word "Warning". It is a combustible liquid (H227) with a flash point of 75-113°C . It causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. 4-Ethoxybenzaldehyde may be harmful if swallowed. It is toxic to aquatic life with long-lasting effects (H412) . Thermal decomposition or combustion produces toxic and irritating fumes, including carbon oxides .
3. Always consult 4-Ethoxybenzaldehyde the specific Safety Data Sheet (SDS) for 4-Ethoxybenzaldehyde for complete hazard information, first-aid procedures, and handling instructions. Precautionary statements include P210 (keep away from heat/sparks/open flames), P261 (avoid breathing vapors), P280 (wear protective gloves/eye protection), and P403+P235 (store in a well-ventilated place, keep cool) .
