705-86-2 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 705-86-2 differently. You can refer to the following data:
1. clear colorless to light yellow oily liquid
2. 5-Decanolide is a flavor constituent of many types of fruit, cheese, and other dairy products. It is a colorless, viscous liquid with a creamy-coconut, peach-like aroma.
3. δ-Decalactone has an oily, peach odor and taste.


Reported found in rum, coconut, raspberry, apricot, bilberry, peach, strawberry, Swiss cheese, other cheeses, butter, milk, milk powder, mutton fat, mango and nectarine.


Used in pharmaceutical preparations, feed additive, flavorings agent. Also used by food and flavor industries for its coconut fragrance and taste. It is also used as a reagent in the synthesis of (±)-Massoilactone (M197600); a chemical component with antibacterial activity found in volatile oils.


δ-Decalactone can be prepared by peracid oxidation of 2-pentylcyclopentanone. (R)-δ-decalactone is obtained in high optical purity by starting from (R)-2- pentylcyclopentanone . Hydrogenation or fermentation of massoia lactone is also a practicable method to produce this enantiomer. A newer development for the preparation ofδ-decalactone describes a carboxylation of 1-nonen-4-ol with carbon monoxide in the presence of a homogenous palladium catalyst in an aqueous system.


ChEBI: A delta-lactone that is 5-valerolactone substituted by a pentyl group at position 6.

Check Digit Verification of cas no

The CAS Registry Mumber 705-86-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 705-86:
72 % 10 = 2
So 705-86-2 is a valid CAS Registry Number.
