CAS No.:100-52-7
1.2 Properties 
Appearance & Characters: Pure chemicals are colorless transparent liquid, and industrial products are colorless to pale yellow.
Boiling point: 179℃
Freezing point: -26℃
Specific gravity:( ρH2O =1):1.04;(ρAir =1):3.66
Solubility: Benzaldehyde is poorly soluble in water; soluble in a variety of organic solvents like benzene, ethyl alcohol,ehtyl ether and chloroform.
Flash point: 64℃
Self-ignition point: 192℃
Hazard properties: Benzaldehyde is flammable when near heat, open flame or oxidant.
Stability: Benzaldehyde is stable under common conditions.
Chemical reactions will take place when it contacts with strong oxidizer, strong acids, air and so on.
1.3 Main Applications
It is widely applied to the fields such as syntheses of pharmaceuticals, perfumes and so on.
2. Packing, Storage and Transportation
2.1 Packing
Packing material: Polyvinyl chloride
Standard for net weight: 200kg/drum
2.2 Storage
Benzaldehyde should be stored in a cool, well-ventilated warehouse, kept away from ignition sources, heat and flame, and avoided exposing to direct sunshine. It is better to be packed in sealed PVC bags under nitrogen air at a pitch and stored separately from oxidant.
2.3 Transportation
Be careful when handing and protect against any damage of the package and container.
