Application

Phenylacetaldehyde is a naturally occurring aromatic aldehyde found in flowers, essential oils, and various fruits. It is a versatile building block widely used across multiple industries.

In the fragrance and flavor industry, phenylacetaldehyde is a key ingredient in perfumes and flavorings, providing a sweet, floral aroma that enhances various products. It is an active component of fragrances and floral scents due to its honey-like sweet character. It is primarily used in hyacinth, narcissus, rose, and clove fragrance formulations, and is widely applied in perfumes, cosmetics, and food essences. In flavor applications, it contributes honey, sweet, floral, chocolate, cocoa, and spicy notes, and is used in flavored cigarettes and beverages.

In pharmaceutical and organic synthesis, phenylacetaldehyde serves as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. It is a building block for more complex chemicals such as resmethrin (a synthetic pyrethroid insecticide). It is also used in the preparation of fragrances and polymers like polyesters, finding application as a rate controlling additive in polymerization reactions. Additionally, it is employed in the synthesis of Schiff bases for the determination of trace rare earth metal ions in food.

In agricultural and pest control applications, phenylacetaldehyde is an insect attractant utilized in blacklight traps for pests.

Custom Synthesis Support

We offer custom synthesis for phenylacetaldehyde derivatives including deuterated analogs, higher purity grades (99.0 percent and above), and stabilized formulations. Custom packaging under inert atmosphere is available. Share your technical datasheet for feasibility review.

Packaging and Shipping

Available in 500 mL, 1 L, 5 L, 20 L, 200 L steel drums or IBC totes. Custom packaging such as amber glass bottles with PTFE lined caps under nitrogen is supported. Fastest dispatch within 7 days after order confirmation.

Phenylacetaldehyde is a highly flammable liquid, UN 1170, Class 3, Packing Group II. Store in a cool place at 2 to 8 degrees Celsius under inert atmosphere. The compound is air sensitive and tends to polymerize on standing, becoming more viscous. It can be reconverted to the monomer by distillation. Incompatible with strong oxidizing agents and strong bases. Keep container tightly closed and away from sources of ignition.

Why XinChem

XinChem provides phenylacetaldehyde with strict control of purity, acid value, and odor profile for US customers.

Trusted by numerous fragrance houses, flavor companies, and pharmaceutical research groups in North America. We also provide free sample evaluation for qualified R&D projects and a price match guarantee against any valid competitor quote for equivalent quality. All shipments are packaged under nitrogen to prevent oxidation and polymerization, with clear handling instructions.

FAQ

Q1 How should phenylacetaldehyde be stored to prevent polymerization?
A Store in a cool place at 2 to 8 degrees Celsius under inert atmosphere (nitrogen or argon). Keep container tightly sealed and protected from light and air. The compound polymerizes on standing and becomes more viscous. If polymerization occurs, it can be reconverted to the monomer by distillation. Shelf life is 3 months or longer if stored properly.

Q2 What purity grades do you supply?
A Standard grade is 95.0 percent minimum by GC. We also supply 98.0 percent grade for pharmaceutical and high-end fragrance applications, and 99.0 percent grade for analytical reference standards.

Q3 Is phenylacetaldehyde soluble in water?
A Phenylacetaldehyde is slightly soluble in water (2.210 g per L at 25 degrees Celsius). It is miscible with ethanol, diethyl ether, propylene glycol, and most organic solvents.

Q4 Do you provide sample quantities for fragrance development?
A Yes, free samples of 100 mL are available for qualified US companies. Shipping fee applies for small quantities.

Q5 What are the common impurities and how do you control them?
A Key impurities include oxidation products (phenylacetic acid) and polymerization oligomers. Our specification limits acid value to 5.0 max KOH per g. Full impurity profiling is provided per batch.

Q6 Is phenylacetaldehyde approved for use as a food flavoring?
A Yes, it is FEMA GRAS (No. 2874), FDA 21 CFR 172.515 compliant, and approved by JECFA and EU regulations 1334/2008 and 178/2002. Please request our regulatory package for your specific application.
