Lactobionic Acid SDS GHS MSDS Sheet of Manufacturers
Lactobionic acid (4-O-β-galactopyranosyl-D-gluconic acid) is a sugar acid. It is a disaccharide formed from gluconic acid and galactose. It can be formed by oxidation of lactose. Lactobionic acid is also used in the cosmetics industry as an antioxidant and in the pharmaceutical industry as an excipient for formulation.
Specifications of Lactobionic Acid USP NF Grade:
C12H22O12 (acid form) --- 358.30 --- CAS 96-82-2.

DEFINITION
Mixture in variable proportions of 4-O-b-D-galactopyranosyl-D-gluconic acid and 4-O-b-Dgalactopyranosyl-D-glucono-1,5-lactone.
Content: 98.0 per cent to 102.0 per cent (anhydrous substance).
CHARACTERS
Appearance: White or almost white powder.
Solubility: Freely soluble in water, slightly soluble in glacial acetic acid, in anhydrous ethanol and in methanol.
mp: About 125C with decomposition.
IDENTIFICATION
A. Infrared absorption spectrophotometry. To pass the test.
TESTS
Appearance of solution: The solution is clear and not more intensely coloured than reference.
Specific optical rotation: + 23.0 to + 29.0 (anhydrous substance).
Dissolve 1.0 g in 80 ml of water and dilute to 100.0 ml with the same solvent. Allow to stand for 24 h.
Reducing sugars: To pass the test. Maximum 0.2 per cent, calculated as glucose.
Heavy metals: Maximum 20 ppm.
Water: Maximum 5.0 per cent, determined on 0.50 g.
Total ash: Maximum 0.2 per cent.
Dissolve 0.350 g in 50 ml of carbon dioxide-free water, previously heated to 30C. Immediately titrate with 0.1 M sodium hydroxide and determine the 2 equivalence points potentiometrically.
The first equivalence point (V1) corresponds to the acid form of lactobionic acid and the second equivalence point (V2 - V1) corresponds to the d-lactone form.
1 ml of 0.1 M sodium hydroxide is equivalent to 35.83 mg of C12H22O12.
1 ml of 0.1 M sodium hydroxide is equivalent to 34.03 mg of C12H20O11.
The sum of the 2 results is expressed as a percentage content of lactobionic acid.
