Pivaldehyde CAS 630-19-3

1. Pivaldehyde CAS 630-19-3 is primarily used as a building block in organic synthesis, particularly in stereoselective synthesis and aldol condensation reactions . It serves as a key raw material and intermediate for pharmaceuticals, agrochemicals, and dyestuffs .
2. The compound is valued in cosmetic intermediate synthesis for its highly branched neopentyl structure, which imparts low volatility, high stability, and mild chemical reactivity . Pivaldehyde is used to prepare key fragrance ingredients (e.g., lyral) and special esters .
3. Applications of Pivaldehyde also include its use in preparing bulky ligands, resins, and specialty chemicals where its sterically hindered structure provides unique reactivity .

1. Store Pivaldehyde CAS 630-19-3 in a tightly sealed container under an inert gas (e.g., nitrogen) in a cool place. Recommended storage temperatures are refrigerated (2-8°C) to maintain stability, as Pivaldehyde is air, light, and heat sensitive . Desiccate to protect from moisture .
2. Keep Pivaldehyde strictly away from heat, sparks, open flames, and incompatible materials including strong oxidizing agents, strong reducing agents, and strong bases . Containers must be grounded and bonded to prevent electrostatic discharge .
3. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves, protective clothing, and eye/face protection. Use only with adequate ventilation or in a fume hood, and avoid breathing vapors, mist, or gas .

1. Immediately isolate the spill area, eliminate all ignition sources, and provide adequate ventilation. Contain Pivaldehyde CAS 630-19-3 using inert, non-combustible absorbent material and prevent entry into drains or waterways .
2. Carefully collect Pivaldehyde using non-sparking tools or an explosion-proof vacuum 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) during cleanup. Pivaldehyde is classified for transport.

1. Pivaldehyde CAS 630-19-3 is classified as a highly flammable liquid and vapor (H225, Danger) with a flash point ranging from -15°C to 20°C . It causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. Pivaldehyde is harmful if swallowed . Its vapors are heavier than air and may form explosive mixtures with air. Thermal decomposition produces toxic and irritating fumes including carbon monoxide and carbon dioxide . It is virtually insoluble in water but soluble in chloroform .
3. Always Pivaldehyde consult the specific Safety Data Sheet (SDS) for Pivaldehyde for complete hazard information, first-aid procedures, and handling instructions. Precautionary statements include P210 (keep away from heat/sparks/open flames), P233 (keep container tightly closed), P240 (ground/bond container), P241 (use explosion-proof equipment), and P280 (wear protective gloves/eye protection) .
