MMAI - marquis reagent color

[tomtom73]

does anybody know, which color MMAI would turn with a marquis test?
i've got a quite dark brown after seconds, but can't find any reference on the web.
a second reaction (mecke, mandelin..) for MMAI would be nice too.

same thing with O-desmethyltramadol. i guess it wouldn't change color at all with the marquis test, right?

thx!

I would guess the reactions would be similar to MDMAI and MDAI, but don't quote me on that as I am not familiar with MMAI...

i've both here, MDAI gives light brown and fades to darker brown.
MDMAI gives me a middle orange-brown, which also gets darker with time.

the MMAI sample to be checked gave a very dark brown color almost instantly, very similiar to the brown which MDAI gives after a couple of minutes.
