Heptaldehyde CAS 111-71-7

1. Heptaldehyde is primarily used as a key building block in the flavor and fragrance industry for synthesizing ingredients with fruity and floral notes, such as α-amylcinnamaldehyde and various acetals . It is naturally found in foods like apricot, fish, and mushroom .
2. Heptaldehyde CAS 111-71-7 serves as a bio-based and sustainable intermediate in organic synthesis for producing pharmaceuticals, agrochemicals, specialty chemicals, and polymer additives . A notable source is castor oil, making it a 100% renewable building block .
3. Applications of Heptaldehyde also include its use as a curing agent in polymer processing and as a reagent in analytical chemistry .

1. Store Heptaldehyde in a tightly sealed container in a cool, dry, and well-ventilated area, away from heat, sparks, and open flames. Recommended storage temperatures range from refrigeration (0-8 °C) to a cool, dark place below 15°C .
2. Keep Heptaldehyde away from strong oxidizing agents, strong acids, and strong bases due to its flammability and incompatibility . It can form explosive mixtures with air.
3. Always Heptaldehyde CAS 111-71-7 use appropriate personal protective equipment (PPE) including chemical-resistant gloves, safety goggles, and protective clothing. Use only with adequate ventilation or in a fume hood to avoid breathing vapors .

1. Immediately isolate the spill area and eliminate all ignition sources. Contain Heptaldehyde using inert, non-combustible absorbent material (e.g., dry sand) and prevent entry into drains or waterways .
2. Carefully collect Heptaldehyde CAS 111-71-7 into a sealed, labeled chemical waste container for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE including self-contained breathing apparatus (SCBA) if necessary during cleanup. Heptaldehyde is classified for transport (UN3056, Hazard Class 3, PG III) .

1. Heptaldehyde is classified as a flammable liquid and vapor (H226) . It causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. Heptaldehyde is harmful if swallowed, inhaled, or absorbed through the skin, with reported oral LD50 values ranging from 3200 mg/kg to 14,000 mg/kg in rats . Heptaldehyde CAS 111-71-7 is toxic to aquatic life with long-lasting effects (H412) .
3. Always consult the specific Safety Data Sheet (SDS) for Heptaldehyde for complete hazard information, first-aid procedures (P303+P361+P353 for skin, P305+P351+P338 for eyes), and handling instructions. Precautionary statements include P210 (keep away from heat/sparks/open flames), P240 (ground/bond container), and P280 (wear protective gloves/eye protection) .
