C₂H₂O₄ ഫോർമുലയോടുകൂടിയ ഒരു ഓർഗാനിക് സംയുക്തമാണ് ഓക്സാലിക് ആസിഡ്. വർണ്ണരഹിതമായ പരൽ രൂപത്തിലുള്ള പദാർത്ഥമായ ഓക്സാലിക് ആസിഡ് ജലത്തിൽ നിറമില്ലാത്ത ഒരു ലായനിയാണ്. HooCCOOH ആണ് ഇതിന്റെ ഘടന, ഡൈകാർബോക്സിലിക് ആസിഡായ ഈ ആസിഡ് അസെറ്റിക് ആസിഡിനേക്കാൾ അമ്ലവീര്യം വളരെ കൂടുതലാണ്. ഓക്സാലിക് ആസിഡ് ഒരു നിരോക്സീകാരിയാണ്. ^[8]ഇതിന്റെ സംയുഗ്മകക്ഷാരം (conjugate base) ഓക്സലേറ്റ് (C
₂O²⁻
₄) എന്നറിയപ്പെടുന്നു.
