Oxalic acid and its salts in the textile and leather industries as a mordant; as a component of anode baths for Al, Ti and Sn skin surfaces; as a reagent in analytical and organic chemistry; components of compositions for cleaning metals from rust and oxides; for the formation of rare earth elements. Oxamide is a stabilizer of cellulose nitrates, cyan is a reagent in organic synthesis, oxalyl chloride is a chlorinating, chlorocarbonylating and crosslinking reagent in organic synthesis. Dialkyl oxalates, mainly diethyl oxalate and dibutyl oxalate, are used as solvents for cellulose; some esters of oxalic acid and substituted phenols are used as chemiluminescent reagents.
