L-Tryptophan SDS of Manufacturers
Synonyms: L-Tryptophan or (S)-2-Amino-3-(3-indolyl)propionic Acid or L-α-Amino-3-indolepropionic Acid
CAS Number: 73-22-3, Molecular Weight: 204.23, Chemical Formula: C11H12N2O2, EINECS EC Number: 200-795-6, FEMA: ----,
L-Tryptophan or (S)-2-Amino-3-(3-indolyl)propionic acid or L-α-Amino-3-indolepropionic acid is an amino acid, a protein building block. People use L-tryptophan for severe PMS symptoms and for quitting smoking. It is also used for athletic performance, depression, insomnia, and many other conditions.
Tryptophan USP Grade Specifications:
C11H12N2O2 204.23
l-Tryptophan CAS 73-22-3
UNII: 8DUH1N11BX
DEFINITION
Tryptophan contains NLT 98.5% and NMT 101.5% of C11H12N2O2, asl-tryptophan, calculated on the dried basis.
IDENTIFICATION
Infrared Absorption
ASSAY
Procedure:
Sample solution: Place 200 mg of Tryptophan in a 125-mL flask. Dissolve in a mixture of 3 mL of formic acid and 50 mL of glacial acetic acid.
Analysis: Titrate with 0.1 N perchloric acid, determining the endpoint potentiometrically. Perform a blank determination and make any necessary correction. Each mL of 0.1 N perchloric acid is equivalent to 20.42 mg of C11H12N2O2.
Acceptance criteria: 98.5%–101.5% on the dried basis.
IMPURITIES
Residue on Ignition: NMT 0.1%
Chloride and Sulfate, Chloride: A 0.73-g portion shows no more chloride than corresponds to 0.50 mL of 0.020 N hydrochloric acid (0.05%). [Note— Gently heat the sample preparation to dissolve, if necessary.]
Chloride and Sulfate, Sulfate: A 0.33-g portion shows no more sulfate than corresponds to 0.10 mL of 0.020 N sulfuric acid (0.03%). [Note— Gently heat the sample preparation to dissolve, if necessary.]
Iron: NMT 30 ppm.
Organic Impurities: to pass the tests by chromatography.
Optical Rotation, Specific Rotation: −29.4° to −32.8°
Sample solution: 10 mg/mL, in water. [Note— Heat gently to dissolve, if necessary.]
pH: 5.5–7.0, in a solution (1 in 100).
Loss on Drying: Dry a sample at 105° for 3 h: it loses NMT 0.3% of its weight.
Tryptophan BP Ph Eur Grade Specifications:
C11H12N2O2 --- 204.2 CAS 73-22-3
DEFINITION
(2S)-2-Amino-3-(1H-indol-3-yl)propanoic acid.
Product of fermentation or of protein hydrolysis.
Content: 98.5 per cent to 101.0 per cent (dried substance).
CHARACTERS
Appearance: White or almost white, crystalline or amorphous powder.
Solubility: Sparingly soluble in water, slightly soluble in ethanol (96 per cent). It dissolves in dilute solutions of mineral acids and alkali hydroxides.
IDENTIFICATION
First identification: A, B
Second identification: A, C, D
A. Specific optical rotation.
B. Infrared absorption spectrophotometry.
C. Thin-layer chromatography.
D. Dissolve about 20 mg in 10 mL of water. Add 5 mL of dimethylaminobenzaldehyde solution and 2 mL of hydrochloric acid. Heat on a water-bath. A purple blue colour develops.
Appearance of solution: The solution is clear and not more intensely coloured than reference solution.
Dissolve 0.1 g in 1 M hydrochloric acid and dilute to 10 mL with the same acid.
Specific optical rotation: -33.0 to -30.0 (dried substance).
Dissolve 0.25 g in water, heating on a water-bath if necessary, and dilute to 25.0 mL with the same solvent.
Ninhydrin-positive substances: To pass the test.
Impurity A and other related substances: To pass the test.
