Store 4-Biphenylcarboxaldehyde CAS 3218-36-8 (white crystalline powder, mp 58-60℃, density 1.12g/cm³, bp 328℃, purity ≥98%, air/light-sensitive, prone to oxidation) at 5–25℃ in sealed amber glass/HDPE drums in a cool, dark, dry area, away from fire, strong oxidants and acids. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; store under inert gas for long-term preservation.

4-Biphenylcarboxaldehyde CAS 3218-36-8 is an industrial aromatic aldehyde with low acute toxicity, only mild skin irritation with prolonged contact; unregulated storage may cause oxidation to carboxylic acid impurities.

In regulated use, 4-Biphenylcarboxaldehyde CAS 3218-36-8 features high reactivity in condensation reactions, good solubility in aromatic/ether solvents, excellent thermal stability during synthesis, and the biphenyl core enhances molecular rigidity for high-performance material synthesis with high yield.
