EC number: 269-052-1
CAS number: 68186-90-3
This substance is identified in the Colour Index by Colour Index Constitution Number, C.I. 77310.
Trial 1 was not considered acceptable
because of cell culture problems (slower growth; positive control
cultures were excessively cytotoxic; the vehicle control mutant
frequencies, while still in the acceptable range, were higher than
usual). However, no mutagenicity of the test substance was observed.
Suspension growth *a
Cloning efficiency *b
Relative growth *c
Mutant frequency (10e-6units)*d
*a = relative to vehicle control
*b = relative to vehicle control,
total viable colony count/number of cells seeded * 100
*c = (relative suspension growth +
relative cloning efficiency) / 100
*d = relative to vehicle control,
(total mutant colonies/ total viable colonies) * 2 * 10e-4,
decimal is moved to express the frequency in units of 10e-6.
