Methyl Hydroxybenzoate or Methylparaben

Specifications of Methylparaben USP NF Grade:
C8H8O3 --- 152.15
Benzoic acid, 4-hydroxy-, methyl ester.
Methyl p-hydroxybenzoate --- CAS 99-76-3.

Methylparaben contains not less than 98 percent and not more than 102 percent of C8H8O3.

A: Infrared Absorption.
B: Melting range: between 125 and 128.
Color of solution: Dissolve 1 g in alcohol, dilute with alcohol to 10 mL, and mix (Methylparaben solution). This solution is clear and not more intensely colored than alcohol or a solution prepared immediately before use by mixing 2.4 mL of ferric chloride, 1.0 mL of cobaltous chloride and 0.4 mL of cupric sulfate with 0.3 N hydrochloric acid to make 10 mL and diluting 5 mL of this solution with 0.3 N hydrochloric acid to make 100 mL. Make the comparison by viewing the solutions downward in matched color-comparison tubes against a white surface.
Acidity: To 2 mL of Methylparaben solution prepared in the Color of solution test add 3 mL of alcohol, 5 mL of carbon dioxide-free water and 0.1 mL of bromocresol green and titrate with 0.10 N sodium hydroxide: not more than 0.1 mL is required to produce a blue color.
Residue on ignition: not more than 0.1%, determined on 1.0 g.
Related substances: To pass the test.

C8H8O3 --- Formula weight: 152.15
INS: 218 CAS: 99-76-3

Methylparaben occurs as small, colorless crystals or as a white, crystalline powder. One gram dissolves in about 400 mL of water at 25C, in about 50 mL of water at 80C, in about 2.5 mL of alcohol, in about 7 mL of ether, and in about 4 mL of propylene glycol. It is slightly soluble in glycerin and in fixed oils.
Function: Preservative; antimicrobial agent.

Identification: Dissolve 500 mg of sample in 10 mL of 1 N sodium hydroxide, boil for 30 min, allow the solution to evaporate to a volume of about 5 mL, and cool. Acidify the solution with 2 N sulfuric acid, collect the crystals on a filter, wash several times with small portions of water, and dry in a desiccator over silica gel. The p-hydroxybenzoic acid so obtained melts between 212C and 217C.
Assay: Not less than 99.0% and not more than 100.5% of C8H8O3, calculated on the dried basis.
Acidity: Passes test.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 0.5%.
Melting Range: Between 125C and 128C.
Residue on Ignition: Not more than 0.05%.
