Styrallyl Acetate, chemically known as 1-phenylethyl acetate, is a synthetic organic compound with the molecular formula C10H12O2 and a molecular weight of 164.20 g/mol. It is classified as an ester and falls under the category of aroma chemicals, widely utilized for its significant contributions to both fragrance and flavor compositions. Typically appearing as a clear, colorless to pale yellow liquid, its most defining characteristic is its complex odor profile. This profile is often described as a potent, penetrating green-leafy scent, strongly reminiscent of gardenia, but also encompassing fruity nuances such as rhubarb, apple, and apricot. Depending on its concentration and context, it can also exhibit subtle metallic or musty undertones.

The production of Styrallyl Acetate commonly involves the direct esterification of acetic acid with methylphenylmethanol, often conducted under azeotropic conditions to drive the reaction to completion. This synthetic pathway ensures a consistent and high-purity product, critical for its demanding applications in perfumery and flavor creation. Its physical properties, such as a refractive index around 1.493-1.497 and a relative density of approximately 1.023-1.028 at 25°C, are standard specifications monitored for quality control.

In the fragrance industry, Styrallyl Acetate is highly valued for its role in creating floral accords, particularly gardenia and tuberose, and for adding a characteristic dry, fresh, fruity top-note to many other fragrance types. Its strength and diffusibility make it effective even at low concentrations, allowing for precise olfactory adjustments. Similarly, in the flavor sector, it is an important component for crafting raspberry, pineapple, tea, and vegetable flavors, contributing to the overall profile and vibrancy.
