DL-Methionine Racemethionine SDS of Manufacturers
Synonyms: DL-Methionine or Racemethionine or DL-2-amino-4-methylithio butanoic acid
CAS Number: 59-51-8, Molecular Weight: 149.21, Chemical Formula: C5H11NO2S, EINECS EC Number: 200-432-1, FEMA: 3301,
DL Methionine is an amino acid that produces several important molecules in your body. These molecules are essential for the proper functioning of your cells. Methionine essential amino acid in humans. It is largely used in animal feed.
Specifications of DL-Methionine BP Ph Eur Grade:
C5H11NO2S --- 149.2 --- 59-51-8
Action and use: Used in treatment of paracetamol overdose.
DEFINITION
DL-Methionine contains not less than 99.0 per cent and not more than the equivalent of 101.0 per cent of (2RS)-2-amino-4-(methylsulfanyl)butanoic acid, calculated with reference to the dried substance.
CHARACTERS
Almost white, crystalline powder or small flakes, sparingly soluble in water, very slightly soluble in alcohol. It dissolves in dilute acids and in dilute solutions of the alkali hydroxides.
It melts at about 270C (instantaneous method).
IDENTIFICATION
First identification: A, C
Second identification: B, C, D
A. Examine by infrared absorption spectrophotometry, comparing with the spectrum obtained with DL-methionine CRS. Dry the substances at 105C.
B. Examine the chromatograms obtained in the test for related substances. The principal spot in the chromatogram obtained with test solution (b) is similar in position, colour and size to the principal spot in the chromatogram obtained with reference solution (a).
C. Dissolve 2.50 g in 1 M hydrochloric acid and dilute to 50.0 mL with the same acid. The angle of optical rotation is -0.05° to + 0.05°.
D. Dissolve 0.1 g of the substance to be examined and 0.1 g of glycine in 4.5 mL of dilute sodium hydroxide solution. Add 1 mL of a 25 g/L solution of sodium nitroprusside. Heat to 40C for 10 min. Allow to cool and add 2 mL of a mixture of 1 volume of phosphoric acid and 9 volumes of hydrochloric acid. A deep red colour develops.
TESTS
Solution S: Dissolve 1.0 g in carbon dioxide-free water and dilute to 50 mL with the same solvent.
Appearance of solution: Solution S is clear and colourless.
pH: The pH of solution S is 5.4 to 6.1.
Related substances: To pass the test. --- (0.2 per cent).
Chlorides: Dissolve 0.25 g in 35 mL of water. Add 5 mL of dilute nitric acid and 10 mL of silver nitrate solution. Allow to stand protected from light for 5 min. Any opalescence in the solution is not more intense than that in a standard prepared at the same time in the same manner using a mixture of 10 mL of chloride standard solution (5 ppm Cl) and 25 mL of water (200 ppm). Examine the tubes laterally against a black background.
Sulfates: Dissolve 1.0 g in 20 mL of distilled water, heating to 60C. Cool to 10C and filter. 15 mL of the solution complies with the limit test for sulfates (200 ppm).
Loss on drying: Not more than 0.5 per cent, determined on 1.000 g by drying in an oven at 105C.
Sulfated ash: Not more than 0.1 per cent, determined on 1.0 g.
ASSAY
Dissolve 0.140 g in 3 mL of anhydrous formic acid. Add 30 mL of anhydrous acetic acid. Immediately after dissolution, titrate with 0.1 M perchloric acid, determining the end-point potentiometrically.
1 mL of 0.1 M perchloric acid is equivalent to 14.92 mg of C5H11NO2S.
STORAGE
Store protected from light.
