Chemical Properties

Different sources of media describe the Chemical Properties of 104-67-6 differently. You can refer to the following data:
1. GAMMA-UNDECALACTONE is clear colourless liquid
2. gamma-Undecalactone has a strong, fruity odor suggestive of peach (particularly on dilution). It has a pungent and sweet flavor also similar to peach.

Occurrence

Reported found in hydrolyzed soy protein, butter, peach, apricot and passion fruit. Also reported found in fresh apple, guava fruit, fresh blackberry, heated butter, heated beef fat, ghee, pork fat, yellow passion fruit juice, cooked scented rice, origanum (Spanish) (Coridothymus cap. (L.) Rchb.), mountain papaya, starfruit, plumcot and chicken fat.

Uses

Different sources of media describe the Uses of 104-67-6 differently. You can refer to the following data:
1. Traditionally, the bark and leaves of the peach tree have been used as an anthelmintic, an expectorant, an astringent, and a diuretic, as well as to treat insomnia, cough, and constipation. In the 1970s, peach pits (Laetrile) were a popular but unproved treatment for cancer in other countries. Topically, peach is used to treat minor skin disorders such as burns, abrasions, blisters, scratches, eczema, psoriasis, and warts.
2. 4-Undecanolide is used in the study of primary mutagenicity screening of food additives used in Japan.

Preparation

By the action of sulfuric acid on undecylenic acid; also prepared starting form castor oil; from octanol-1 plus methylacrylate with di-ter-butylperoxide; from heptylethylene oxide and sodiomalonic ester.

Aroma threshold values

Detection: 60 ppb

Taste threshold values

Taste characteristics at 30 ppm: fatty, coconut, creamy, vanilla, nutty, macadamia and peach.

General Description

γ-Undecalactone is a volatile flavor constituent found in low-fat ice cream.

Flammability and Explosibility

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 104-67-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104-67:
(5*1)+(4*0)+(3*4)+(2*6)+(1*7)=36
36 % 10 = 6
So 104-67-6 is a valid CAS Registry Number.
