i·so·cy·an·ic acid

 (ī′-sō-sī-ăn′ĭk)
n.
A caustic and reactive organic acid, HNCO, mainly occurring and used in its ester or salt forms or as its tautomer, cyanic acid, which it forms in aqueous solution. Isocyanic acid is an intermediate in the production of urethanes and has been detected in some comets.
