Amyl propionate

CAS: 624-54-4

Overview

Amyl propionate (CAS 624-54-4 ) is a synthetic ester used commercially as a flavoring and fragrance ingredient. It delivers a characteristic fruity, apple-like aroma profile that makes it a functional raw material for flavor houses.

Fragrance compounders utilize this ester as a building block for various aromatic profiles. In food and beverage manufacturing, it contributes fruity top notes to confectionery, baked goods, and fruit-flavored beverages.

This ingredient is particularly effective where apple and pear character is targeted. Fragrance formulators incorporate it into personal care products, including shampoos, body washes, and lotions, to achieve light, fresh fruit accords.

Flavor compounders use it as a blending component in artificial fruit flavor concentrates supplied to the food processing industry. It also appears in household and industrial fragrance formulations where low-cost fruity character is needed.

The material is supplied as a clear liquid, typically in drum and IBC quantities suited to industrial production. Technical and flavor-grade material is available, with flavor-grade product meeting purity standards for food applications.

Specification documentation including GC purity, refractive index, and density is standard for commercial shipments. This ensures the product meets the rigorous quality requirements of the global chemical and flavoring markets.
