Chemical Structure
Basic Info
Phenylpropylaldehyde (CAS Registry Number: 104-53-0), systematically designated as 3-phenylpropanal or hydrocinnamaldehyde, is an aromatic aldehyde featuring a benzene ring linked to a three-carbon saturated aldehyde side chain. Represented by the molecular formula C₉H₁₀O, it occurs naturally in cinnamomum species, balsam trees, and various fruit volatiles. Phenylpropylaldehyde is highly regarded in fine perfumery and flavor compounding for its warm, balsamic, sweet floral, and green cinnamon-like organoleptic profile.
At Shandong Zhishang Chem Co., Ltd., our Phenylpropylaldehyde is manufactured through controlled catalytic hydrogenation and fractionated distillation processes to achieve a minimum purity of 98.0%. It serves as an indispensable aroma building block, flavor reconstituting agent, and versatile organic synthesis intermediate for pharmaceutical and agrochemical precursors.
To satisfy global regulatory standards across the fragrance, flavor, and pharmaceutical intermediate sectors, Shandong Zhishang Chem maintains standardized quality compliance frameworks:
ISO 9001:2015 Quality Management System: Comprehensive oversight covering raw material selective hydrogenation, precision vacuum distillation, nitrogen blanketing, and container filling.
REACH Compliance Support: Technical documentation dossiers provided for European Union chemical importers and formulators.
IFRA Standards Alignment: Produced in accordance with International Fragrance Association guidelines, ensuring strict impurity limits for skin-contact personal care applications.
FEMA & Food Chemicals Codex (FCC) Standards: Adheres to FEMA 2887 criteria for food-grade flavor compounding and natural aroma profile matching.
Aromatic aldehydes are inherently sensitive to atmospheric oxygen and can oxidize into hydrocinnamic acid over extended exposure. To guarantee stability and exact purity, every batch of Phenylpropylaldehyde undergoes a four-stage internal testing protocol before issuing a Certificate of Analysis (COA):
Gas Chromatography (GC-FID / GC-MS): Quantifies purity (≥ 98.0%) and limits isomer or residual alcohol/acid impurities (such as phenylpropanol and hydrocinnamic acid).
Acid Value Titration: Quantitative measurement of free carboxylic acid levels to verify that oxidation state remains strictly within standard limit (≤ 5.0 mg KOH/g).
Organoleptic Odor & Color Profiling: Sensory panel assessment comparing batch odor profiles against reference standards in controlled olfactory testing rooms.
Karl Fischer Moisture Titration: Determines moisture content (≤ 0.2%) to prevent cloudiness and maintain stability during sensitive organic synthesis reactions.

Product Packaging
Phenylpropylaldehyde’s dual functionality—combining a reactive terminal aldehyde group with a floral-balsamic aroma profile—supports broad industrial utility:
Fragrance Compounding: Functions as a key middle-note ingredient in floral (hyacinth, lilac, rose, lily-of-the-valley) and oriental-spicy perfume compositions, adding warm, green, balsamic depth to fine fragrances and household care products.
Flavor Formulation: Reconstitutes natural cinnamon, chocolate, berry, and stone fruit flavor bases used in confectioneries, beverages, and baked goods under FEMA 2887 guidelines.
Organic Synthesis Intermediate: Precursor for synthesizing pharmaceutical intermediates, cinnamic derivatives, specialty substituted propanols, and fine chemical building blocks.
Personal Care & Cosmetic Products: Utilized in soap, shampoo, and body wash formulations due to its excellent alkali resistance compared to unsubstituted cinnamaldehyde.

Q1: How should Phenylpropylaldehyde (CAS 104-53-0) be stored to prevent oxidation?
A: Phenylpropylaldehyde should be stored in tightly sealed, light-resistant aluminum-lined or stainless steel drums under an inert nitrogen gas blanket. Keep in a cool, dry, dark warehouse below 25°C away from strong oxidizers and direct sunlight.
Q2: What is the main structural and olfactory difference between Phenylpropylaldehyde and Cinnamaldehyde?
A: Phenylpropylaldehyde has a saturated three-carbon side chain (C9H10O), whereas Cinnamaldehyde contains an alpha,beta-unsaturated double bond (C9H8O). Olfactorily, Phenylpropylaldehyde is softer, greener, more floral, and less pungent/irritating than cinnamaldehyde, offering superior chemical stability in alkaline media.
