Sodium Propionate Pure & IP BP USP NF FCC Food Grade Manufacturers,
We manufacture Sodium Propionate in all grades like Commercial Pure, IP BP USP NF FCC etc. Typical specifications are given below.
Sodium Propionate Commercial Food Grade & Pure
C3H5NaO2 Formula wt 96.06
INS: 281 CAS: [137-40-6]
Sodium Propionate occurs as white or colorless, transparent crystals or as a granular, crystalline powder. It is hygroscopic in moist air. One gram is soluble in about 1 mL of water at 25°, in about 0.65 mL of boiling water, and in about 24 mL of alcohol. The pH of a 1:10 aqueous solution is between 8.0 and 10.5.
Function: Preservative; mold inhibitor.
A. A 1:20 aqueous solution gives positive tests for Sodium.
B. Upon ignition, a sample yields an alkaline residue that effervesces with acids.
C. Warm a small sample with sulfuric acid. Propionic acid, recognized by its odor, evolves.
Assay: Not less than 99.0% and not more than 100.5% of C3H5NaO2 after drying.
Alkalinity (as Na2CO3): Passes test (about 0.15%).
Iron: Not more than 0.003%.
Lead: Not more than 2 mg/kg.
Water: Not more than 1%.

B. Dissolve 0.1 g in a mixture of 2 ml of copper sulphate solution and 2 ml of methylene chloride. Shake vigorously and allow to stand. Both the upper and the lower layer show a blue colour.
C. To 5 ml of solution S add 2 ml of 0.1 M silver nitrate. A white precipitate is formed.
D. Solution S gives reaction of sodium.
Dissolve 10 g Sodium propionate in carbon dioxide-free water prepared from distilled water and dilute to 100 ml with the same solvent.
Appearance of solution
Solution S is clear and colourless.
7.8 to 9.2
Dilute 1 ml of solution S to 5 ml with water.
Test solution: Dissolve 0.250 g of the substance to be examined in water and dilute to 100 ml with the same solvent.
Reference solution (a) Dissolve 10 mg of the substance to be examined and 10 mg of sodium acetate in water and dilute to 100 ml with the same solvent.
Reference solution (b) Dilute 1.0 ml of the test solution to 100 ml with water.
Readily oxidizable substances
In a ground-glass-stoppered conical flask introduce 10 g of the substance ( Sodium propionate.) to be examined.
Add 100 ml of water R and stir to dissolve. Add 25 ml of sodium hypobromite solution and 10 ml of a 200 g/l solution of sodium acetate, stopper the flask and allow to stand for 15 min. Add 10 ml of potassium iodide solution and 20 ml of hydrochloric acid while cooling.
Titrate with 0.2 M sodium thiosulphate, adding 2 ml of starch solution R towards the end of the titration. Carry out a blank titration. The difference between the volumes used in the 2 titrations is not greater than 2.2 ml.
Maximum 10 ppm.
10 ml of solution S complies with the limit test for iron.
Maximum 10 ppm.
12 ml of solution S complies with limit test A. Prepare the standard using lead standard solution (1 ppm Pb).
Loss on drying
Maximum 0.5 per cent, determined on 1.000 g by heating in an oven at 105C for 3 h.
Dissolve 80.0 mg Sodium propionate in 30 ml of anhydrous acetic acid R. Titrate with 0.1 M perchloric acid, determining the end-point potentiometrically.
1 ml of 0.1 M perchloric acid is equivalent to 9.61 mg of C3H5NaO2.
Sodium Propionate USP NF
Propanoic acid, sodium salt, hydrate.
Sodium propionate hydrate [6700-17-0]
Anhydrous 96.06 [137-40-6]
Sodium Propionate, dried at 105 for 2 hours, contains not less than 99.0 percent and not more than 100.5 percent of C3H5NaO2.
A: Infrared Absorption 197K , on un-dried specimen.
B: A solution (1 in 20) responds to the tests for Sodium.
Alkalinity Dissolve 2.0 g in 20 mL of water, and add phenolphthalein TS: if a pink color is produced, it is discharged by 0.60 mL of 0.10 N sulfuric acid.
Water: not more than 1.0%.
Heavy metals Dissolve 2 g in 1 mL of 1 N acetic acid and sufficient water to make 25 mL: the limit is 0.001%.
Organic volatile impurities: meets the requirements.
(Official until July 1, 2007)
Assay Dissolve about 200 mg of Sodium Propionate, previously dried at 105 for 2 hours and accurately weighed, in 50 mL of glacial acetic acid. Add 1 drop of crystal violet TS, and titrate with 0.1 N perchloric acid VS to a green endpoint. Perform a blank determination, and make any necessary correction. Each mL of 0.1 N perchloric acid is equivalent to 9.606 mg of C3H5NaO2.

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.
They assign the credit of their hard work to your blessings
They keep you amused.
They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.
They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.
They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.
They offer you a small bribe as advance for booty, called lottery
They love to dream.
I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
