Ethane-1,2-dicarboxilic Acid or Butanedioic Acid or Succinic Acid
CAS Number: 110-15-6
Molecular Formula: HOOCCH2CH2COOH
Molecular Weight: 118.09
Ethane-1,2-dicarboxilic Acid or Butanedioic Acid or Succinic Acid
Succinic Acid USP NF Grade Specifications:
C4H6O4 --- 118.09
Butanedioic acid CAS 110-15-6
Succinic Acid contains not less than 99.0 percent and not more than 100.5 percent of C4H6O4.
Identification: Place a drop of a saturated solution of the sample in a micro test-tube and add a drop of ammonium chloride solution (0.5 in 100) and several mg of zinc powder. Cover the mouth of the tube with a disk of filter paper moistened with a solution in hexane containing pdimethylaminobenzaldehyde (5 in 100) and trichloroacetic acid (20 in 100). Heat with a small flame for about 1 minute: a pink to red-violet stain appears on the paper.
Melting range: between 185.0 and 190.0.
Residue on ignition: not more than 0.025%.
Heavy metals: 0.002%.
Assay: Dissolve about 250 mg, accurately weighed, in 25 mL of carbon dioxide-free water. Add 2 drops of PhPh and titrate with 0.1 N sodium hydroxide to the production of a permanent pink color. Each mL of 0.1 N sodium hydroxide is equivalent to 5.905 mg of C4H6O4.
