Structural Formula
Basic Info
Ethyl Isovalerate (CAS Registry Number: 108-64-5), systematically designated as ethyl 3-methylbutyrate, is a short-chain branched aliphatic ester naturally occurring in fruits such as apples, pineapples, strawberries, and grapes. Synthesized through controlled esterification of isovaleric acid with ethanol, it exhibits a diffusive, sweet aroma characterized by fresh apple, pineapple, and tropical fruit notes.
At Shandong Zhishang Chem Co., Ltd., our Ethyl Isovalerate is produced under strict process control to ensure an assay purity of ≥99.0%. It serves as an essential flavor ingredient and aroma chemical across food processing, beverage compounding, confectionery, tobacco, and fine fragrance formulations.

To support seamless integration into food, beverage, and cosmetic supply chains, Shandong Zhishang Chem adheres strictly to international quality and food safety frameworks:
ISO 9001:2015 Certification: Governs synthesis, fractional distillation, drumming, and warehouse storage processes.
ISO 22000 & FSSC 22000 Alignment: Robust food safety management protocol maintaining strict hygiene, zero cross-contamination, and complete lot traceability.
Kosher & Halal Certified: Fully verified by accredited religious bodies for global dietary compliance.
Regulatory Compliance: Aligned with Food Chemicals Codex (FCC), European Union flavor standard (FL-No: 09.447), and FEMA guidelines (FEMA 2463).
To guarantee organoleptic fidelity and physical purity, every production batch of Ethyl Isovalerate undergoes four-stage internal testing prior to Certificate of Analysis (COA) release:
Gas Chromatography (GC-FID) Assay: Verifies chemical purity (≥99.0%) and ensures minimal presence of unreacted isovaleric acid or free ethanol residues.
Refractive Index & Specific Gravity Profiling: Confirms exact chemical structure and physical consistency across production runs.
Acid Value Titration: Measures residual free acidity to prevent harsh or sour off-notes in delicate beverage formulations.
Organoleptic Evaluation: Evaluated by trained flavorists to ensure consistent fruity, apple-like top notes without unexpected background odors.
Ethyl Isovalerate’s high volatility and radiant ester profile make it a versatile ingredient across multiple sectors:
Food & Beverage Flavoring: Enhances natural fruit profiles in soft drinks, fruit juices, dairy desserts, hard candies, and chewing gums, imparting fresh apple, berry, and pineapple notes.
Fragrance & Fine Perfumery: Functions as a fresh top-note modifier in body mists, fine perfumes, and personal care products, providing an uplifting fruity accord.
Tobacco & Vapor Formulations: Introduces subtle sweet undertones to specialty tobacco blends and electronic vapor liquids, rounding off harsh tobacco notes.
Pharmaceutical Taste Masking: Helps mask bitter active ingredients in oral liquids and chewable formulations with pleasant fruity top notes.

Q1: What aroma profile does Ethyl Isovalerate contribute to flavor formulations?
A: Ethyl Isovalerate provides a sweet, ethereal, fruity top note reminiscent of ripe apples, pineapples, and tropical fruits. Its low odor threshold enables flavorists to introduce fresh fruitiness at low concentration levels.
Q2: What is the recommended usage concentration of Ethyl Isovalerate in food products?
A: Typical dosage varies by food matrix, generally ranging from 1 ppm to 20 ppm in finished beverages and up to 50 ppm in confectionery and bakery applications. Bench-scale trial additions are recommended to optimize performance.
Q3: How should Ethyl Isovalerate be stored to maintain long-term stability?
A: Store in full, tightly sealed containers in a cool, dry, and dark warehouse away from heat sources and strong oxidizing agents. Under nitrogen headspace and recommended ambient conditions, the shelf life is 24 months.
Q4: What documentation accompanies bulk export shipments?
A: Each shipment includes a lot-specific Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS), Kosher/Halal certificates, Technical Data Sheet (TDS), and Non-GMO declaration upon request.
