Formula (1)< Conversion 1 > (In formula, n1 and n2 shows each integer 3 - 10 in the respective independence.As for A, carbonyl group and oxy carbonyl group, -S (O) n11 - (as for n11, 0, 1 or 2 is shown.)And so on it shows, R1 shows the hydrocarbon radical which is possible to have possessed the substituent. R2 - R9, in the respective independence, shows the hydrogen atom and the like. R10 - R13, in the respective independence, shows the hydrogen atom and the like.)So guanidine chemical compound and those salts which are displayed, or the sterilization characteristic composition which contains these.式(1)【化1】〔式中、n1及びn2は、それぞれ独立に3~10のいずれかの整数を示す。Aは、カルボニル基、オキシカルボニル基、-S(O)n11-(n11は、0、1、または2を示す。)等を示し、R1は置換基を有していてもよい炭化水素基を示す。R2~R9は、それぞれ独立に、水素原子等を示す。R10~R13は、それぞれ独立に、水素原子等を示す。〕で表されるグアニジン化合物及びそれらの塩、又はこれらを含有する殺菌性組成物。
