How can buyers verify that Cinnamaldehyde CAS 104-55-2 matches cinnamic aldehyde in technical documents?

Buyers usually confirm identity by checking the CAS number 104-55-2 together with the EC number 203-213-9, molecular formula C9H8O, and the accepted chemical names Cinnamaldehyde or cinnamic aldehyde on the SDS, TDS, and COA.

Is Cinnamaldehyde typically used as a fragrance formulation raw material or as a chemical intermediate?

It can be used in both contexts. In commercial practice, one supply line may be positioned for aroma or fragrance processing, while another may be purchased as a fine chemical input for synthesis or formulation work. The exact fit depends on grade, purity target, and documentation requirements.

Cinnamaldehyde CAS 104-55-2

Cinnamaldehyde is an aromatic aldehyde used in the Fine Chemical and Basic & Fine Chemicals supply chain as a reactive organic compound for formulation and process use, and this material, also known in technical trade language as cinnamic aldehyde, cinnamal, (E)-3-phenylprop-2-enal, and 3-phenyl-2-propenal, corresponding to CAS 104-55-2, is characterized by its conjugated aldehyde structure that contributes aldehydic reactivity and odor-active functionality, making it commonly applied in flavor and fragrance processing, aroma chemical blending, and selected chemical intermediate systems where controlled identity and composition are required; This product is typically offered with competitive factory pricing, customized specifications, document support including MSDS, TDS, COA, and stable bulk supply.

Applications

1. Flavor and fragrance processing
Cinnamaldehyde is commonly used as an aroma chemical raw material in flavor and fragrance systems where a defined aldehydic cinnamon profile is required.

2. Chemical intermediate use
Its conjugated aldehyde structure allows it to serve as an intermediate or building block in selected fine chemical synthesis routes.

3. R&D and formulation screening
It is also used in laboratory and pilot-scale formulation work for identity-controlled aromatic aldehyde input.

Storage & Safety

Store in a cool, dry, and well-ventilated area. Keep the container tightly closed. Protect from direct sunlight, heat sources, and ignition sources. Avoid contact with strong oxidizing agents and strong bases. During handling, use suitable PPE including chemical-resistant gloves, protective goggles, and protective clothing. Local exhaust ventilation is recommended for bulk transfer or repeated handling. Avoid direct skin contact and inhalation of vapors. Follow the current SDS for industrial handling, spill response, and disposal procedures.

Quality Assurance

A credible factory quality program for cinnamaldehyde usually includes identity and purity control by GC, with additional confirmation methods such as GC-MS or NMR when needed for higher-traceability supply. Routine release items often include assay, appearance, color, density, refractive index, and selected impurity checks. If the material is intended for regulated downstream sectors, documentation control, batch traceability, and the applicable plant quality system should be confirmed case by case. GMP status should not be assumed unless the specific manufacturing site and grade are explicitly declared as such.
