CAS Number 112-38-9 Undecylenic Acid, EINECS: 203-965-8, Molecular Weight: 184.28, Chemical Formula: CH2=CH(CH2)8COOH

Specifications of Undecylenic Acid USP Grade:
C11H20O2 --- 184.28
10-Undecenoic acid.
10-Undecenoic acid --- CAS 112-38-9

Undecylenic Acid contains not less than 97.0 percent and not more than 100.5 percent of C11H20O2.

Packaging and storage: Preserve in tight, light-resistant containers.
Identification:
A: To 1 mL add potassium permanganate, dropwise: the permanganate color is discharged.
B: Place 3 mL of it and 3 mL of freshly distilled aniline in a tall test tube, and heat for 10 minutes at a rate such that the ring of condensate remains just below the mouth of the tube. Cool, add 10 mL of alcohol and 10 mL of ether, and transfer to a separator. Wash the ether solution with four 20-mL portions of water and discard the water washings. Heat on a steam bath until the odor of ether no longer is perceptible, then add a few mg of activated carbon, mix, and filter. Evaporate the filtrate nearly to dryness, and recrystallize the residue from 70 percent alcohol: the anilide so obtained melts between 66 and 67.5 .
Specific gravity: between 0.910 and 0.913.
Congealing range: not lower than 21 .
Refractive index: between 1.447 and 1.448.
Residue on ignition: not more than 0.15%.
Water-soluble acids: Shake 5 mL with 5 mL of water, and filter the water layer through a filter paper previously moistened with water. Add 1 drop of methyl orange, and titrate with 0.01 N sodium hydroxide: not more than 1.0 mL of 0.010 N sodium hydroxide is required to match the color produced by 1 drop of methyl orange in 5 mL of water.
Heavy metals: 0.001%.
Iodine value: between 131 and 138.

Specifications of Undecenoic Acid BP Grade, Ph Eur:
C11H20O2 --- 184.3 --- CAS 112-38-9

DEFINITION
Undec-10-enoic acid.
Content: 97.0 per cent to 102.0 per cent.

CHARACTERS
Appearance: White or very pale yellow, crystalline mass or colourless or pale-yellow liquid.
Solubility: Practically insoluble in water, freely soluble in ethanol (96 per cent) and in fatty and essential oils.

IDENTIFICATION
A. Refractive index: 1.447 to 1.450, determined at 25 ± 0.5C.
B. Freezing point: 21C to 24C.
C. To 2.0 g add 2 mL of freshly distilled aniline and boil under a reflux condenser for 10 min. Allow to cool and add 30 mL of ether. Shake with 3 quantities, each of 20 mL, of dilute hydrochloric acid and then with 20 mL of water. Evaporate the organic layer to dryness on a water-bath. After re-crystallising twice from ethanol (70 per cent V/V) and drying in vacuo for 3 h, the residue melts at 66C to 68C.
D. Dissolve 0.1 g in a mixture of 2 mL of dilute sulfuric acid and 5 mL of glacial acetic acid. Add dropwise 0.25 mL of potassium permanganate solution. The colour of the potassium permanganate is discharged.

TESTS
Peroxide value: Maximum 10.
Fixed and mineral oils: To 1.0 g add 5 mL of sodium carbonate solution and 25 mL of water and boil for 3 min. The hot solution is not more opalescent than reference suspension.
Water-soluble acids: To 1.0 g add 20 mL of water heated to 35-45C and shake for 2 min. Cool and filter the aqueous layer through a moistened filter. To 10 mL of the filtrate add 0.1 mL of phph solution. Not more than 0.1 mL of 0.1 M sodium hydroxide is required to change the colour of the indicator.
Degree of unsaturation: Dissolve 85.0 mg in a mixture of 5 mL of dilute hydrochloric acid and 30 mL of glacial acetic acid. Using 0.05 mL of indigo carmine solution as indicator, added towards the end of the titration, titrate with0.0167 M bromide-bromate until the colour changes from blue to yellow. 8.9 mL to 9.4 mL of0.0167 M bromide-bromate is required. Carry out a blank titration.
Sulphated ash: Maximum 0.1 per cent, determined on 0.50 g.
