Claim:
A compound having the formula: wherein R is a C 1-12 straight chain alkyl, a C 3-12 branched chain alkyl, a C 2-12 straight chain or a C 3-12 branched chain olefinic, a C 1-12 acyl, sulfonyl, carboxamido, a glycosyl group, a C 1 –C 30 aryl group or a group of the formula —(CH 2 ) n- ON═N(O)NR 28 R 29 , wherein n is an integer of 2–8, and R 28 and R 29 are independently a C 1-12 straight chain alkyl, a C 3-12 branched chain alkyl, or a C 2-12 straight chain or a C 3-12 branched chain olefinic, or R 28 and R 29 , together with the nitrogen atom to which they are bonded, form a heterocyclic group selected from the group consisting of a pyrrolidino, a piperidino, a piperazino and a morpholino group; and R 22 is hydrogen, hydroxyl, OM, wherein M is a cation, a halo, X 1 R 23 R 24 , wherein X 1 is O, N or S, and R 23 and R 24 are independently a C 1-24 alkyl, a C 3-24 cycloalkyl, a C 2-24 olefinic, a C 3 –C 30 aryl, or a heterocyclic group, and, when X 1 is O or S, there is no R 24 .
