    I looked at some places where I have bought special chems and the stuff is frightfully expensive. Fischer Scientific wants $285 for 100g.

    Neocyanine is an IR sensitizer i thought there might be some emulsion making going on here. I'm almost out of IR film.

    If the OP is looking for a negative retouching dye, that should work. If the OP is looking for an infrared sensitizing dye for film, the crocein scarlet probably won't.

    There are several cyanine derivatives that can be used. I don't have the link anymore, but somewhere in this emulsion making subforum, PE posted a page from an old Eastman Organic Chemicals list that had the common names and chemical names of some infrared sensitizers. A couple of these are being sold by Chemsavers (on the web) by their chemical names.

    OK, I found PE's list here:

    Anyway, chemsavers still has a couple of the carbo-cyanines listed above.

    Lab Depot, Science Lab and Colonial Scientific sell a number of those dyes as well. Chemsavers selection has been limited lately.

    The CROCEIN SCARLET dye structure does not look like a sensitizing dye at all.

    All this has happened before, and all this will happen again.

    Looking for some for possible emulsion making, as well as re-sensitizing x-ray film to hopefully give it some infrared sensitivity. I have heard that this may be possible, so I'd like to give it a try. I too, am almost out of IR film.
