Syringic acid Usage And Synthesis

Chemical Properties

light brown powder

Uses

antiproliferative; antifungal

Definition

ChEBI: A dimethoxybenzene that is 3,5-dimethyl ether derivative of gallic acid.

Purification Methods

Recrystallise syringic acid from H2O using charcoal [Bogert & Coyne J Am Chem Soc 51 571 1929, Anderson & Nabenhauer J Am Chem Soc 48 3001 1926.] The methyl ester has m 107o (from MeOH), the 4-acetyl derivative has m 190o and the 4-benzoyl derivative has m 229-232o. [Hahn & Wassmuth Chem Ber 67 2050 1934, UV: Lemon J Am Chem Soc 69 2998 1947 and Pearl & Beyer J Am Chem Soc 72 1743 1950, Beilstein 10 IV 1995.]
