Chemical Structure
Basic Info
Hexyl Isovalerate (CAS Registry Number: 10032-13-0), chemically classified as Hexyl 3-methylbutanoate (FEMA: 2575, EINECS: 233-097-4), is a specialty aliphatic ester formed via the condensation of 1-hexanol with isovaleric acid. Naturally identified in traces across fruits such as apples, bananas, grapes, and tea leaves, this clear ester is recognized for its vibrant fruity green character.

FAQ
A: Hexyl Isovalerate contributes a crisp, natural green-fruity top note that mimics the fresh skin character of ripe apples, pears, and tropical fruits. It effectively enhances initial impact and freshness when blended with longer-chain esters and lactones.
A: Store in tightly sealed aluminum bottles, stainless steel containers, or lined steel drums under an inert nitrogen blanket. Keep in a cool, dry, well-ventilated location away from direct sunlight, open flames, and strong oxidizing agents. Under proper conditions, typical shelf life is 24 months.
A: Standard packaging options include 25 kg fluorinated plastic drums, 180 kg lined steel drums (nitrogen purged), and custom small-scale containers for evaluation samples. Batch-specific COA, SDS, and technical datasheets accompany all shipments.

Laboratory Self-Inspection & Batch Verification Workflow
Esters utilized in fine fragrance and flavor systems demand exact chemical purity to prevent off-odors caused by unreacted residual acids or alcohols. Every batch of Hexyl Isovalerate undergoes comprehensive multi-stage internal laboratory validation prior to releasing the official Certificate of Analysis (COA):
High-Resolution Gas Chromatography (GC-FID): Quantifies main ester purity (>= 98.0%) while establishing strict maximum limits on residual 1-hexanol and free isovaleric acid to maintain an authentic odor profile.
Acid Value Potentiometric Titration: Measures residual acidity (<= 1.0 mg KOH/g), ensuring product stability and preventing corrosive degradation during storage or further compounding.
Optical & Physical Refraction Screening: Verifies specific gravity and refractive index values against reference baselines using automated refractometry to confirm physical uniformity across production lots.
Professional Olfactory Evaluation: Conducted by experienced sensory specialists comparing lot samples against standardized reference materials under controlled ambient conditions to ensure top-note freshness and sensory consistency.
