ASSAY
• PROCEDURE
Sample: 150 mg of Glycine
Blank: 100 mL of glacial acetic acid
Titrimetric system
(See Titrimetry <541>.)
Mode: Direct titration
Titrant: 0.1 N per chloric acid VS
Endpoint detection: Visual
Analysis: Dissolve the Sample in 100 mL of glacial acetic acid, and add 1 drop of crystal violet TS. Titrate with the Titrant to a green endpoint. Perform the Blank determination.
Calculate the percentage of glycine (C2H5NO2) in the Sample taken:
Result = {[(VS − VB) × N × F]/W} × 100
VS = Titrant volume consumed by the Sample (mL)

Glycine, when dried, contains not less than 98.5% of Glycine(C2H5NO2).
Description Glycine occurs as white, crystals orcrystalline powder. It has a sweet taste. It is freely soluble in water and in formic acid, and practically insoluble in ethanol (95). It shows crystal polymorphism.
Identification Determine the infrared absorption spectrum of Glycine, previously dried, as directed in the potassiumbromide disk method under Infrared Spectrophotometry <2.25>, and compare the spectrum with the Reference Spec-trum: both spectra exhibit similar intensities of absorption atthe same wave numbers. If any difference appears between the spectra, dissolve Glycine in water, evaporate the water todryness, and repeat the test with the residue.
pH <2.54> Dissolve 1.0 g of Glycine in 20 mL of water: thepH of the solution is between 5.6 and 6.6.
Purity
(1) Clarity and color of solution-Dissolve 1.0 gof Glycine in 10 mL of water: the solution is clear and color-less.
(2) Chloride <1.03>-Perform the test with 0.5 g of Glycine. Prepare the control solution with 0.30 mL of 0.01mol/L hydrochloric acid VS (not more than 0.021%)
(3) Sulfate <1.14>-Perform the test with 0.6 g of Glycine. Prepare the control solution with 0.35 mL of 0.005mol/L sulfuric acid VS (not more than 0.028z).
(4) Ammonium <1.02>-Perform the test using 0.25 g of Glycine. Prepare the control solution with 5.0 mL of Standard Ammonium Solution (not more than 0.02%).
(5) Heavy Metals <1.07>-Proceed with 1.0 g of Glycine according to Method 1, and perform the test. Prepare the control solution with 2.0 mL of Standard Lead Solution (notmore than 20 ppm).
(6) Arsenic <1.11>-Prepare the test solution with 1.0 gof Glycine according to Method 1, and perform the test (notmore than 2 ppm).
(7) Related Substences-Dissolve 0.10 g of Glycine in 25mL of water and use this solution as the sample solution. Pipet 1 mL of the sample solution, add water to make exactly 50 mL. Pipet 5 mL of this solution, add water to makeexactly 20 mL, and use this solution as the standard solution.Perform the test with these solutions as directed under Thin-layer Chromatography<2.03>. Spot 5mL each of the sample solution and standard solution on a plate of silica gel forthin-layer chromatography. Develop the plate with a mixture of 1-butanol, water and acetic acid (100) (3:1:1) to a distance of about 10 cm, and dry the plate at 80℃ for 30 minutes. Spray evenly a solution of ninhydrin in acetone (1 in 50), andheat at 80℃ for 5 minutes: the spots other than the principal spot from the sample solution are not more intense than the spot from the standard solution.
Loss on Drying <2.41> Not more than 0.30% (1 g, 105℃, 3 hours).
Residue on Ignition <2.44> Not more than 0.10% (1g).
Assay Weigh accurately about 80 mg of Glycine, previously dried, dissolve in 3 mL of formic acid, add 50 mL of acetic acid (100), and titrate <2.50> with 0.1 mol/L perchloric acid VS (potentiometric titration). Perform a blank determi-nation, and make any necessary correction.

Glycine (H-Gly-OH) (CAS: 56-40-6) is of the simplest structure in the 20 members of amino acid series, also known as amino acetate. It is a non-essential amino acid for the human body and contains both acidic and basic functional group inside its molecule. Used for the pharmaceutical industry, organic synthesis and biochemical analysis. Used as a buffer for the preparation of tissue culture media and the testing of copper, gold and silver. In medicine, it is used for the treatment of myasthenia gravis and progressive muscular atrophy, hyperacidity, chronic enteritis, and children hyperprolinemia diseases, using in combination with aspirin can reduce the irritation of the stomach; treatment of children hyperprolinemia; as the nitrogen source for generating non-essential amino acid and can be added to a mixed amino acid injection. Glycine is primarily used as a nutritional additive in chicken feed. Used as a kind of nutritional supplement which is mainly used for flavoring. Flavoring agent: Used for alcoholic beverage in combination with alanine; In pharmacy, it is used as antacids (hyperacidity), therapeutic agent for muscle nutritional disorder as well as antidotes.

In the field of pesticide production, it is used for synthesizing the glycine ethyl ester hydrochloride which is the intermediate for the synthesis of pyrethroid insecticides. Moreover, it can also be used for synthesizing fungicides iprodione and solid glyphosate herbicide; in addition it is also used in various kinds of other industries such as fertilizer, medicine, food additives, and spices. Used as a solvent to remove carbon dioxide in the fertilizer industry. In the pharmaceutical industry, it can be used as amino acid preparations, the buffer of chlortetracycline buffer and as the raw material for synthesizing the anti-Parkinson's disease drugs L-dopa. Moreover, it is also the intermediate for producing ethyl imidazole. It is also an adjunct therapy medicine for treating neural hyperacidity and effectively suppressing excess amount of gastric ulcer acid. In the food industry, it is used for the synthesis of alcohol, brewing products, meat processing and cold drinks formula. As a food additive, glycine can be used alone as a condiment and also used in combination with sodium glutamate, DL-alanine acid, and citric acid. In other industries, it can be used as a pH adjusting agent, being added to the plating solution, or used as the raw material for making other amino acids. It can further be used as biochemical reagents and solvent in organic synthesis and biochemistry. In pharmaceutical industry, it is used as the buffer of chlortetracycline, amino antacids.
