Overview
Hydrocinnamaldehyde (CAS 104-53-0 ), also known as 3-phenylpropanal, is an aromatic aldehyde used as a flavoring and fragrance ingredient across food and personal care markets.
It delivers a warm, sweet, floral-balsamic character that perfumers and flavorists use to build complex scent and taste profiles. In fragrance formulation, it functions as a heart or base note.
This chemical is used in fine perfumes, soaps, and household products, contributing a soft hyacinth-like warmth. Food and beverage manufacturers incorporate it as a flavoring agent under FEMA 2887 .
It is particularly useful in baked goods, confectionery, and fruit-forward flavor systems. In personal care, it appears in body lotions, shampoos, and cosmetic creams where a lasting note is required.
The compound also serves as a synthetic intermediate for more complex aroma chemicals and pharmaceutical building blocks. It is supplied as a clear to pale yellow liquid in standard packaging.
Food-grade material is available in compliance with industry designations, and technical-grade material is offered for industrial fragrance and synthesis applications. Purity specifications typically range from 98% upward.
Documentation is available to support both flavor and cosmetic regulatory requirements. Our supply chain ensures consistent quality for all industrial, food, and fragrance manufacturing needs.
