    Abstract: 1-OH-2-acyl-sn-glycero-3-phosphocholine compounds and its analogs, pure or mixed, having formula WCH2CHXCH2PO3YCH2CH2Z, where W is preferably a hydroxyl group or an O-acyl group containing from 2 to 22 carbon atoms, and where X is preferably an O-acyl group containing from 2 to 22 carbon atoms or a hydroxyl (OH) and where Y may be an (O?) or OH and where Z is preferably a trimethyl-ammonium group [N+(CH3)3] can be protonated dimethyl ammonium [N+H(CH3)2] group. In the O-acyl groups containing 18 carbon atoms can be observed from 0 to 3 instaurations, useful as biocidal agents; processes for their preparation; and antifouling compositions, preferably paints useful in susceptible fouling surfaces, such as hulls of vessels.
