EC number: 205-565-9
CAS number: 142-84-7
Toxic effects, evident as a reduction in the number of revertants (below the induction factor of 0.5), were observed at the following concentrations (µg/plate):
without S9 mix
with S9 mix
2500 – 5000
2500 - 5000
/ = no toxic effects (induction factor ≥ 0.5)
n.p. = not performed
No substantial increase in revertant colony numbers of any of the five tester strains was observed following treatment with Dipropylamine at any concentration level, neither in the presence nor absence of metabolic activation (S9 mix). There was also no tendency of higher mutation rates with increasing concentrations in the range below the generally acknowledged border of biological relevance.
Appropriate reference mutagens were used as positive controls. They showed a distinct increase in induced revertant colonies.
