Zinc Undecenoate BP Ph Eur Grade Specifications (It is also called Zinc Undecylenate)
Ph Eur
C22H38O4Zn -- 431.9 -- CAS Number 557-08-4
Action and use: Used topically in treatment of fungal infections.
DEFINITION
Zinc di(undec-10-enoate).
Content: 98.0 per cent to 102.0 per cent (dried substance).
CHARACTERS
Appearance: White or almost white, fine powder.
Solubility: Practically insoluble in water and in ethanol (96 per cent).
mp: 116C to 121C, it may leave a slight solid residue.
IDENTIFICATION
A. To 2.5 g add 10 ml of water and 10 ml of dilute sulphuric acid. Shake with 2 quantities, each of 10 ml, of ether. Reserve the aqueous layer for identification test C. Wash the combined ether layers with water and evaporate to dryness. To the residue 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.
The residue, after recrystallisation twice from ethanol (70 per cent V/V) R and drying in vacuo for 3 h, melts at 66C to 68C.
B. Dissolve 0.1 g in a mixture of 2 ml of dilute sulphuric acid and 5 ml of glacial acetic acid. Add drop-wise 0.25 ml of potassium permanganate solution. The colour of the potassium permanganate solution is discharged.
C. A mixture of 1 ml of the aqueous layer obtained in identification test A and 4 ml of water gives the reaction of zinc.
TESTS
Alkalinity: Mix 1.0 g with 5 ml of ethanol (96 per cent) and 0.5 ml of phenol red solution. Add 50 ml of carbon dioxide-free water and examine immediately. No reddish colour appears.
Alkali and alkaline-earth metals: Maximum 2.0 per cent.
To 1.0 g add 25 ml of water and 5 ml of hydrochloric acid and heat to boiling. Filter whilst hot. Wash the filter and the residue with 25 ml of hot water. Combine the filtrate and washings and add concentrated ammonia until alkaline. Add 7.5 ml of thioacetamide solution and heat on a water-bath for 30 min. Filter and wash the precipitate with 2 quantities, each of 10 ml, of water. Combine the filtrate and washings, evaporate to dryness on a water-bath and ignite. The residue weighs a maximum of 20 mg.
Sulphates: Maximum 500 ppm.
Loss on drying: Maximum 1.5 per cent, determined on 0.500 g by drying in an oven at 105C.
Degree of un-saturation: Dissolve 0.100 g in a mixture of 5 ml of dilute hydrochloric acid R and 30 ml of glacial acetic acid. Using 0.05 ml indigo carmine solution, added towards the end of the titration as indicator. Titrate with 0.0167 M bromide-bromate until the colour changes from blue to yellow.
9.1 ml to 9.4 ml of 0.0167 M bromide-bromate is required. Carry out a blank titration.
ASSAY
To 0.350 g add 25 ml of dilute acetic acid and heat to boiling. Carry out the complexometric titration of zinc.
1 ml of 0.1 M sodium edetate is equivalent to 43.19 mg of C22H38O4Zn.
