CAS: 61444-38-0Synonyms: Williams Ester Classification: Heart Note[i]
Cis-3-Hexenyl Cis-3-Hexanoate (Williams Ester) opens with a burst of pure pear juice—not sweet or candied, but the fresh, watery essence of biting into ripe fruit. This double-unsaturated ester captures something most materials miss: the textural sensation of pulpiness. You smell the saccharine flesh of the pear, complete with its characteristic ethereal quality.
This material transforms beyond simple pear into complex territory. Its green tomato leaf facets add sharp, vegetal sophistication whilst metallic undertones prevent any cloying sweetness. You can leverage these complex secondary notes to build modern green compositions or use its exceptional 13-hour longevity to anchor fruity top notes deep into the heart.
Use Williams Ester when you need to transcend ordinary fruit notes. Its natural occurrence in gardenia makes it perfect for floral modifications, whilst its melon and tropical facets open doors to aquatic compositions. The key lies in understanding its dual nature—intensely fruity yet surprisingly green.

General Information
General Information
Like most suppliers and makers of quality raw materials for fragrances, we do not filter many of our products. This ensures that no odiferous matter is lost prior to use but can result in the appearance of small particles or slight clouding.
All alcoholic fragrances should be macerated for up to a month and then chilled in a moderate freezer overnight before being filtered fine. This will remove all cloudiness or detritus and is the industry norm.
