Maleic acid may be used to form acid addition salts with drugs to make them more stable, such as indacaterol maleate. It is used for making Maleate Salts of Bulk-Drugs like Pheneramine Maleate, Chloropheneramine Maleate and others. It is also used to prevent rancidity in oils. Maleic acid has become a new acidulant in food and beverage industry. It can enhance special fruit aroma and improve the taste in food and beverage. At the present time Maleic acid is mainly used in syrup, ready-tea, orange juice, sports beverage and other fortified syrup and food. In addition, Maleic acid is mainly used to manufacture unsaturated polyester resin, pesticide, tartaric acid, fumaric acid, succinic acid, DL-Malic acid, dyeing auxiliary and preservative grease.
Maleic Acid BP
C4H4O4 -- 116.1 -- 110-16-7
DEFINITION
Maleic acid contains not less than 99.0 per cent and not more
than the equivalent of 101.0 per cent of (Z)-butenedioic
acid, calculated with reference to the anhydrous substance.
CHARACTERS
A white, crystalline powder, freely soluble in water and in alcohol.
IDENTIFICATION
A. Dilute 5 ml of solution S (see Tests) to
10 ml with water. The pH of the dilution is less than 2.
B. Examine the chromatograms
obtained in the test for fumaric acid. The
principal spot in the chromatogram obtained with test solution (b) is
similar in position and size to the principal spot in the chromatogram
obtained with reference solution (a).
C. Dissolve 0.1 g in 10 ml of
water (solution a). To 0.3 ml of solution (a) add a solution of
10 mg of resorcinol in 3 ml of sulphuric
acid. Heat on a water-bath for 15 min; no
colour develops. To 3 ml of solution (a) add 1 ml of bromine
water. Heat on a water-bath to remove the bromine (15 min), heat to
boiling and cool. To 0.2 ml of this solution add a solution of 10 mg of
resorcinol in 3 ml of sulphuric
acid. Heat on a water-bath for 15 min. A violet-pink
colour develops.
TESTS
Solution S
Dissolve 5.0 g in water R and dilute to 50 ml with the same
solvent.
Appearance of solution
Solution S is clear and not more intensely
coloured than reference solution.
Fumaric acid
To pass the test
Iron
To 10 ml of solution S add 2 ml of dilute hydrochloric acid
and 0.05 ml of bromine water. After 5
min, remove the excess of bromine by passing a current of air and add 3
ml of potassium thiocyanate solution.
Shake. Prepare a standard at the same time and in the same manner,
using a mixture of 5 ml of iron standard solution (1
ppm Fe) R, 1 ml of dilute
hydrochloric acid, 6 ml of water and 0.05 ml of bromine
water. Allow both solutions to stand for 5 min. Any red
colour in the test
solution is not more intense than that in the standard (5
ppm).
Heavy metals
1.0 g complies with limit test D for
heavy metals (10 ppm).
Water
Not more than 2.0 per cent, determined on 1.00 g by the semi-micro
determination of water.
Sulphated ash
Not more than 0.1 per cent, determined on 1.0 g.
Maleic Acid USP
Maleic Acid
C4H4O4 116.07
(Z)-Butenedioic acid
Cis-Butenedioic
acid [110-16-7].
Maleic Acid contains not less than
99.0 percent and not more than 101.0 percent of C4H4O4, calculated on
the anhydrous basis.
Identification—
A:
Dissolve about 500 mg of Maleic Acid
in 10 mL of water: the pH of the solution is
less than 2.
B: To pass chromatography test
C: Dissolve about 35 mg of resorcinol in 10
mL of sulfuric acid (Resorcinol solution). Dissolve about
100 mg of Maleic Acid in 10
mL of water (Test solution). To 0.3
mL of the Test solution add 3
mL of the Resorcinol solution, and
heat in a water bath for 15 minutes: no color develops. To 3
mL of the Test solution add 1
mL of bromine TS, heat in a water bath for
15 minutes to remove the bromine, then heat to boiling, and cool. To 0.2
mL of this solution, add 3
mL of the Resorcinol solution, and
heat in a water bath for 15 minutes: a violet-pink color develops.
Color and clarity of solution—
Dilute hydrochloric acid solution— Mix 27.5
mL of hydrochloric acid with sufficient
water to make 1000 mL.
Reference solution— Mix 2.4 mL of
ferric chloride CS and 0.6 mL of
cobaltous chloride CS with Dilute
hydrochloric acid solution to make 10 mL.
Dilute 5 mL of this solution with Dilute hydrochloric acid solution
to make 100 mL.
Test solution— Dissolve about 5 g of Maleic
Acid in 50 mL of water.
Procedure— Place the Reference solution
and the Test
solution in matched color-comparison tubes, and compare the
solutions by viewing them downward against a white surface : the
Test solution is clear and not more
intensely colored than the Reference solution.
Water: not more than 2.0% is found.
Residue on ignition: not more than 0.1%, determined on a 1.0-g
portion.
Heavy metals— not more than 10 µg per g.
Limit of fumaric acid— To pass the
test
Limit of iron—: not more than 5 µg per g.
