N-Oxy-2-pyridylisothiourea derivatives as bactericides and fungicides: N-Oxy-2-pyridylisothiourea derivatives as bactericides and fungicides. Yamaguchi, Taiichi; Sakaguchi, Junei; Mitsui, Susumu; Hirai, Hiroharu; Takeuchi, Yosuke (Somar Mfg. Co., Ltd., Japan). Japan. Kokai JP 51133425 19 Nov 1976 Showa, 5 pp. (Japanese).Several reagents with their cas registry numbers 62377-10-0 and 103-85-5 are used here. (Japan). CODEN: JKXXAF. CLASS: IC: A01N009-12. APPLICATION: JP 75-56920 13 May 1975. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 27 The 2-pyridylisothiourea oxides I (X = Cl or Br; R1 and R2 = H, Ph,or halophenyl; R1R2=CH2CH2) are bactericides and fungicides. I are sol. in water unlike the corresponding 2-pyridinethiol oxides, and, do not ppt. in the presence of metallic ions. Thus, 2-chloropyridine N-oxide-HCl [20295-64-1] was treated with thiourea [62-56-6] to yield 2-pyridylisothiourea N-oxide-HCl (II) [2770-93-6]. The growth of Aspergillus niger, Penicillium, and Trichoderma was completely inhibited in the presence of 500 ppm II. .

Zinc salts of 2-mercaptopyridine N-oxide: Zinc salts of 2-mercaptopyridine N-oxide. Morinaga, Tsuyoshi; Nakazawa, Yuji; Suzuki, Kunio (Daicel Ltd., Japan). Japan. Kokai JP 51067718 11 Jun 1976 Showa, 4 pp. 2770-93-6 and 3811-73-2 are also occured in this study. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07D213-89. APPLICATION: JP 74-140638 6 Dec 1974. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 62 S-2-pyridylisothiuronium N-oxide halides (I.HX, X = halide) were alkali-decompd. and the mixts. were adjusted to pH 6 and treated with Zn salts to give 2-mercaptopyridine N-oxide Zn salt (II), II is a fungicide and bactericide useful in manuf. of medicated shampoo. Thus, 4.1 g I.HCl in H2O was treated with 2.7 g K2CO3 for 3 h at room temp. (to give III), the pH was adjusted to 6 (HCl) and 15 ml 20% ZnCl2 added to give 95.4% II, contg. no insol. inorg. salts. .
