Basic Info

cis-3-Hexenyl Isovalerate (CAS Registry Number: 35154-45-1), systematically designated as (Z)-3-hexenyl 3-methylbutanoate, is an unsaturated organic ester produced by the esterification of cis-3-hexenol (leaf alcohol) with isovaleric acid. Identified in global flavor and fragrance registries as FEMA 3496 and JECFA 1276, this compound plays a vital role in imparting authentic green, foliage-like freshness accompanied by sweet, ripe fruit notes—notably apple, pear, melon, and tropical nuances.
 
At Shandong Zhishang Chem Co., Ltd., our cis-3-Hexenyl Isovalerate is synthesized under controlled esterification and multi-stage vacuum fractionation processes, achieving a minimum ester assay of 98.0%. It serves as an essential top-to-middle note ingredient for perfumers, flavorists, and specialty chemical formulators.

  • Personal Care & Household Products: Adds a natural, freshly-cut stem and dew-covered fruit freshness to shampoos, body washes, and home care cleaning products.

  • Oral Care & Confectionery: Enhances refreshing green-apple and berry nuance in chewing gums, hard candies, and specialty oral care flavors.

FAQ

A: While all cis-3-hexenyl esters share a green leaf backbone, the isovalerate group adds a distinctive sweet, ripe, fruity apple-pear character with longer tenacity compared to the sharp, ethereal green punch of the acetate ester.

A: Store in tightly sealed glass, aluminum, or lined steel containers in a cool (below 20°C), dry, well-ventilated area away from direct light and oxidizing agents. Purging containers with nitrogen gas helps maintain peak freshness over a 24-month shelf life.

A: Yes. We supply food-grade cis-3-Hexenyl Isovalerate complying with FEMA 3496 specifications. Batch-specific COA, SDS, Kosher/Halal certificates, and allergen statements are provided with every order.

A: We offer 25 kg fluorinated plastic drums, 180 kg steel drums with internal epoxy lining, and custom aluminum bottles for R&D sampling.

Analytical Quality Control & In-House Testing Protocol

Aroma ester performance depends heavily on isomeric purity and low acid residues. Every production batch of cis-3-Hexenyl Isovalerate undergoes internal laboratory testing prior to Certificate of Analysis (COA) release:
 
Capillary Gas Chromatography (GC-FID / GC-MS): Verifies ester assay (≥ 98.0%) and monitors the cis/trans isomer ratio to preserve authentic green organoleptic character.
 
Free Acid Titration: Measures residual unreacted isovaleric acid (≤ 1.0 mg KOH/g) to eliminate harsh or rancid odor notes.
 
Physical Constant Screening: Verifies refractive index and specific gravity parameters against tight batch specifications.
 
Sensory Evaluation Panel: Odor evaluation conducted by professional evaluators in an odor-free environment, comparing batch profiles against reference standards.
