Applicant's summary and conclusion

Conclusions:
N-Methyl-1,3-propanediamine (6291-84-5)was evaluated for its mutagenic potential inSalmonella typhimurium LT2 strains TA 1950 (hisG46, uvrB} ; TS24 (hisG46,recA); TA1537 (hisC3076, uvrB, $a); TA1538 (hisD3052, uvrB, $a}; TA1952(hisC3076, uvrB); and mutant hisG46. The test result was observed to be negative.
Executive summary:

Genetic toxicity in vitro study for N-Methyl-1,3-propanediamine was assessed for its possible mutagenic potential. For this purpose Bacterial reverse mutation assay was performed in Salmonella typhimurium LT2 strains TA 1950 (hisG46, uvrB} ; TS24 (hisG46,recA); TA1537 (hisC3076, uvrB, $a); TA1538 (hisD3052, uvrB, $a}; TA1952(hisC3076, uvrB); and mutant hisG46. No mutagenic effect were observed .Therefore N-Methyl-1,3-propanediamine was considered to be non mutagenic. Hence the test substance cannot be classified as gene mutant in vitro.
