Ethyl Cinnamate: A Specification and Documentation Checklist for Flavor & Fragrance Buyers

Ethyl cinnamate (CAS 103-36-6) is an aromatic ester used as an industrial flavor and fragrance ingredient. Buyers should qualify the exact identity, agreed quality attributes, batch COA, safety information, and destination-specific documentation before purchase—not rely on a generic product description.

For procurement and QC teams, the practical question is not simply whether a supplier can quote ethyl cinnamate. It is whether the material, documents, and intended formulation requirements are aligned well enough to support controlled evaluation and repeat ordering.

What Is Ethyl Cinnamate and How Should Buyers Identify It?

Use the chemical name together with CAS 103-36-6 as the primary purchase identity, then record relevant synonyms in the specification and receiving records.

Ethyl cinnamate is also called cinnamic acid ethyl ester, ethylcinnamate, ethyl cinnamoate, or ethyl (E)-3-phenylprop-2-enoate. The PubChem compound record[1] links these names to CAS 103-36-6 and molecular formula C11H12O2. That is useful for identity screening, but it does not replace a supplier’s current batch documentation.

In an RFQ, record the intended material name, CAS number, physical form required by the formulation, and any buyer-controlled internal material code. This avoids a common failure mode: comparing a quotation, COA, and incoming container that do not all refer to the same agreed substance.

Which Specification Items Should Be Agreed Before Qualification?

Agree only the attributes that are relevant to the intended formulation and release decision, and distinguish contractual limits from typical values.

A product listing can help start a technical conversation, but it is not a release specification. TUODA’s Ethyl Cinnamate product page and flavor and fragrance portfolio are relevant internal starting points; the final specification should be agreed for the proposed project.

For an aromatic ingredient, procurement commonly asks whether identity, assay or purity basis, color or appearance, relevant residuals, water-related criteria where applicable, and odor evaluation need formal acceptance limits. The answer depends on the formulation, analytical method, and change-control approach. Do not copy another supplier’s typical numbers into a purchase specification.

Where a physical property is used in formulation calculations or incoming checks, make the method and temperature basis explicit. The NIST Chemistry WebBook entry[2] is a useful independent reference for identity-related physical-property research, while the agreed batch method remains the release basis.

How Should a COA Be Reviewed Against the Purchase Specification?

A COA is useful only when it is batch-specific and mapped directly to the agreed material and acceptance criteria.

Before releasing an incoming batch, check that the product name, CAS number, lot number, analytical date, units, reported results, and test methods correspond to the PO and approved specification. A result stated only as “pass” may be insufficient where a numeric value, method, or traceable sample link is required by the buyer’s own quality system.

Separate a supplier’s specification from its COA. The first establishes the agreed limits; the second records the analytical result for a stated lot. If the material will be used in a controlled fragrance compound or other customer-qualified formulation, define who reviews changes to method, specification, manufacturing site, or appearance before a later shipment is accepted.

Which Safety, Regulatory, and Use Questions Need Project-Specific Confirmation?

Do not infer finished-product suitability, regulatory status, or handling conditions from a general ingredient description; review the current SDS and the intended market and use case.

Ethyl cinnamate’s appearance in public ingredient inventories does not constitute a TUODA compliance claim or approval for a buyer’s finished product. For fragrance applications, consult the current IFRA Standards Library[3] and have the responsible formulator assess the finished-product category and current requirements. Any food, cosmetic, household, or other end-use decision remains the responsibility of the buyer and applicable specialists.

Request the current grade-specific SDS and review it against site procedures, storage controls, and destination requirements. The OSHA safety-data-sheet appendix[4] explains the standard SDS information structure; it should not be substituted for the supplier’s current product document.

What Should an Ethyl Cinnamate RFQ Include?

A complete RFQ reduces rework by putting formulation, quality, packaging, and destination questions into one controlled review.

TUODA supplies industrial buyers with flavor and fragrance ingredients and can discuss specification alignment, batch review, documentation, packaging, and destination requirements.
