Sodium Feredetate, Solubility Water, CAS Number 12007-89-5, UsageApplication Industrial

Synonyms iron sodium ethylenediaminetetraacetatecas number 15708, 41, 5, Molecular weight 367. 05, Chemical formula c10h12fen2nao8, EC identification number 239, 802, 2, Fema,,,,, Sodium feredetate pH level for blood pressure in Europe grade specificationsc10h21n2o8fena, H2o,, 385. 1,, Cas 15708, 41, 5 definitionsodium feredetate is iron iii sodium ethylenediaminetetra, Acetate monohydrate. It features at least than 98. 0% and no more than 102. 0% of c10h12o8n2fena, Assessed in relation to the dried substance. Characteristicsa yellow or crystalline powder, Hygroscopic. Identificationa. The, Yellowish brown infrared absorption spectrum is concordant with the benchmark spectrum of sodium feredetate. B. Ignite 0. 5 g and allow to cool. Dissolve the residue in A volume of 2 ml of hydrochloric acid, Add sufficient water to produce 20 ml and filter. The filtrate yields reaction c characteristic of iron salts. Dilute 1 volume of the filtrate to 10 volumes the solution, With water yields reaction b characteristic of iron salts. C. Dissolve 2 g available in a 30 ml size of water, Slowly add 6. 5 milliliters worth of a 20% w/v Potassium-based solution hydroxide, Shake and filter the resulting suspension. Evaporate 8 ml of the filtrate to dryness, Ignite and dissolve the residue in 4 mL of water. The solution yields reaction b characteristic of sodium salts. Testsacidity ph of a 1% w/v solution, 4. 0 to 6. 5. Free iron not more than 500 ppm when determined by the following method. Dissolve 0. 2 g in sufficient water to produce 20 ml and filter. Label three tubes a, B and c. Place 5 ml of the filtrate into each of tubes a and b and 4 ml consisting of liquid and 1 ml quantity an robust benchmark offering prepared in the ensuing manner in tube c. For the iron standard solution dilute 25 volumes of a 0. 1726% w/v solution of ammonium iron iii sulphate in 0. 05m sulphuric acid to 200 volumes with water 25 ppm of fe iii . Include 1 ml of a 1. 0% w/v solution of disodium catechol, 3, 5, Disulphonate into each of tubes a and c and 1 ml of water to tube b. Measure the absorbance the answer for a at 670 nm using solution b in the reference cell and of solution c using liquid in the reference cell. The absorbance of solution a is not greater than that of solution c. Heavy metals 1 g adheres to the criteria set by limit test d concerning heavy metals 20 ppm. Free sodium edta to 4 ml of a 1. 0% w/v solution add 2 ml of ferric iron standard solution 50 ppm and 1 ml of a 1. 0% w/v solution of disodium catechol, 3, 5, Disulphonate and mix. Set a conventional standard in the same manner using 4 ml of a 0. 010% w/v solution of disodium edta in place concerning the solution of the substance being examined. Measure the absorbance of the solutions at 670 nm using water in the reference cell. The absorbance of the solution of the substance being examined is no fewer than that of the standard solution 1% . Sulphates dissolve 2 g in 40 ml of water, Include 5 ml of a 20% w/v sodium hydroxide mixed with sufficient water to produce 50 ml, Shake and filter. Evaporate 6. 2 ml of this solution to drynessand ignite until no trace of carbon remains. Cool and dissolve the residue in 10 ml quantity of distilled water. Neutralise the solution with 2m hydrochloric acid using litmus paper as external indicator and add 2 ml in excess. Boil the solution, Cool, Dilute to 15 ml with distilled water and filter. The filtrate complies with the limit test for sulphates 600 ppm. Decrease in water weight during drying when dried over silica gel at 120c at a pressure not exceeding 2 kpa for 5 hours, Loses 4. 0 to 13. 5% of its weight. Use 1 g. For
