<p>(A) Compds. of general formula: (I) R = (1-20C) alkyl, (3-8C) cycloalkyl, or (7-12C) aralkyl. Ac = R' and R2 = (1-20C) alkylidene, (3-8C) cycloalkylidene, or (7-12C) aralkylidene. and R3 = H or HR2 (B) Acid addn. salts of (I). (i) Free bases as buffers or antacids, (ii) Intermediates for urethanes and polyurethane resins (iii) Long-chain cpds. (R2= > 8C alkyl) are wetting agents and emulsifiers (iv) I-HCNS salt condensates with HCHO as corrosion inhibitors (US. 2,425,320; 2,606,155) (v) I.H2SiF6 salts as moth proofers (US. 1,915,334; 2,075,359) (vi) I salts with HAsF6 and HPF6 as anti-parasitics. (vii) Bactericides (those more closely analogous to lincomycin).</p> |
