Benzaldehyde CAS#100-52-7
High Purity and Distinctive Odor – Pure benzaldehyde is a colorless liquid with a characteristic bitter almond aroma, making it suitable for flavoring and fragrance applications.
Stable Physical Properties – With a melting point of -26 °C, boiling point of 179 °C, and flash point of 62 °C, it exhibits stable thermal behavior for industrial use.
Solubility Versatility – Slightly soluble in water but fully miscible with organic solvents such as ethanol, ether, benzene, and chloroform, offering flexibility in formulations.
Consistent Density – Having a density of 1.044 g/cm³ at 20 °C ensures predictable handling and measurement in production processes.
Benzaldehyde, in its pure form, is a colorless liquid, whereas industrial-grade products range from colorless to pale yellow and emit a characteristic bitter almond odor. It has a melting point of -26 °C, a boiling point of 179 °C, a closed-cup flash point of 62 °C, and a density of 1.044 g/cm³ at 20 °C. It is slightly soluble in water and fully miscible with organic solvents such as ethanol, ether, benzene, and chloroform.

Product Usage
Benzaldehyde is primarily used as a chemical raw material for synthesizing compounds such as lauraldehyde and benzyl benzoate, and as an organic solvent. It is also utilized in daily chemical fragrances (including floral blends, soaps, foods, and beverages), pharmaceuticals (for producing phenylglycine, ephedrine, etc.), and pesticides (for manufacturing the herbicide Yeyanqin). Additionally, it serves in the production of dye intermediates, benzylamine, and benzyl alcohol, and is applied as an auxiliary in polyamide dyeing and as an additive in electroplating baths.
