What is Cinnamaldehyde CAS 104-55-2?

Cinnamaldehyde is an aromatic aldehyde with the molecular formula C9H8O and a molecular weight of about 132.16. It is also known as cinnamic aldehyde, cinnamal, or 3-phenyl-2-propenal, and appears as a pale yellow to yellow liquid with a cinnamon-like odor.

Is Cinnamaldehyde available as a natural or synthetic material?

Both routes are possible. Natural cinnamaldehyde can be obtained from cinnamon oil or cinnamon bark, while synthetic material is produced by chemical synthesis. The selected grade depends on the target application, regulatory requirements, and cost profile.

What are the main flavor and fragrance applications?

It is used to create cinnamon-type flavor and fragrance profiles in food, beverage, personal care, household cleaners, and air fresheners. Its characteristic aldehydic cinnamon note makes it useful in both fine fragrance and functional fragrance formulations.

What chemical intermediate and antimicrobial uses does CAS 104-55-2 have?

Its conjugated aldehyde structure makes it a useful building block in selected fine chemical synthesis. Cinnamaldehyde also shows antimicrobial and antifungal activity, so it is studied or used in food preservation, agrochemical, and antibacterial formulation applications.

What are the key specifications of industrial or fine chemical grade?

Typical specifications include a GC assay of at least 98.0%, appearance as a pale yellow to yellow liquid, density around 1.041-1.050 g/cm3 at 20 C, refractive index near 1.622, and boiling point around 248-252 C.

How should Cinnamaldehyde CAS 104-55-2 be stored?

Keep it tightly closed in a cool, dry, well-ventilated area and protect it from direct sunlight, heat, ignition sources, strong oxidizers, and strong bases. Use appropriate gloves, goggles, protective clothing, and ventilation during bulk handling.

Product Description

Cinnamaldehyde CAS 104-55-2, also called cinnamic aldehyde or cinnamal, is an aromatic aldehyde with the molecular formula C9H8O and EINECS 203-213-9.

Synonyms: Cinnamic aldehyde; Cinnamal; (E)-3-phenylprop-2-enal; 3-Phenyl-2-propenal; 3-Phenylprop-2-enal.

CAS: 104-55-2.

Molecular formula: C9H8O.

It is a pale yellow to yellow liquid with a GC assay of not less than 98.0% and a characteristic cinnamon-like odor.

Melting/freezing point is about -7.5 to -8 °C, boiling point about 248-252 °C, and density about 1.041-1.050 g/cm³ at 20 °C.

Refractive index is about 1.622; it is slightly soluble in water and soluble in alcohol and many organic solvent systems.

Vapor density is about 4.6 (air = 1), and flash point is commonly reported around 105-131 °C depending on method.

In flavor and fragrance processing it is an aroma-chemical raw material for defined aldehydic cinnamon profiles.

As a chemical intermediate its conjugated aldehyde structure serves as a building block in selected fine-chemical synthesis.

In R&D and formulation screening it is used for identity-controlled aromatic aldehyde input at laboratory and pilot scale.

It also shows antimicrobial and antifungal activity and is studied or used in food preservation, agrochemical, and antibacterial formulations.

Store in a cool, dry, well-ventilated area with the container tightly closed, protected from sunlight, heat, and ignition sources.

Avoid strong oxidizing agents and strong bases; wear chemical-resistant gloves, goggles, and protective clothing during handling.

Use local exhaust ventilation for bulk transfer or repeated handling; avoid direct skin contact and vapor inhalation.

Every batch is controlled by GC for identity and purity, with GC-MS or NMR confirmation when needed, plus appearance, color, density, refractive index, and impurity checks.

Confirm appearance, assay, color, density, refractive index, boiling point, packaging, and grade as required.
