[edit] Carthamine as alternate name
I just wanted to point out that if you're googling for more info for this article, older references to carthamin seem to spell it carthamine, while the modern dictionary I checked listed carthamin but not carthamine. -Agyle 10:02, 25 September 2007 (UTC)
[edit] Competition with fuchsine
I added a sentence noting it competed with fuchsine as a silk dye, citing an 1860 French source. I'd guess that the fuchsine displaced a lot of carthamin's use after 1860 (I've read that synthetic dyes displaced a lot of natural dye use generally), but I don't have a source for that, so I figured I'd add the more limited statement that I can source. The french passage in question, translated via babelfish.com:
- "It tints silk in 1st purple-red, purple-red, 5 purple, and one can assemble a gamine of the white until tone 4 until the 8th tone, one has the average or about colors called rosy; because the flowers of the rose trees which one can regard as types of rosy are the 6 purple one, the purple-red and the 1 purple-red. The carthamine, applied to silk, generally gives colors going of the 3 purple-red to the red; there can thus be one, two, three, four or five ranges of my chromatic circle ranging between the color of the fuchsine and that of the carthamine, both applied to silk. Before fuchsine, the carthamine gave most beautiful rosy, but it was rosy the least purple, while fuchsine gives the rosy one of the 5 purple, of the purple-red...."
If an English source is found, replacing the French citation would be great; I just happened across this while researching the etymology of fuchsine. -Agyle 10:02, 25 September 2007 (UTC)
[edit] Check mass and formula
Please check the mass and formula...they are inconsistent with the compound on ChemSPider--ChemSpiderMan (talk) 12:43, 9 January 2008 (UTC)
- The mass and formula in this article are consistent with those reported in Chemical Abstracts, PubChem, EINECS and the Merck Index. ChemSpider appears to be the outlier. -- Ed (Edgar181) 14:18, 9 January 2008 (UTC)
- I'm missing something here...I click on the emolecules link and find three compounds...two of mass of 910.78 but with different logP values (so they should be different molecules since they were calculated by the same algorithm) and one with a mass of 450. Then I click on the PubChem link and got a structure of mass 562 and a TOTALLY different structure..so, at least the PubChem link needs changing. The PubChem link is http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=11968069. I checked for the PubChem based InChi and found the structure on ChemSpider here but under the name Carthamine not Carthamin. Thanks to this work I have now curated out the INCORRECT names associated with the structure on ChemSpider.. All carmathine related names are removed from [here http://www.chemspider.com/Chemical-Structure.16736410.html]. I'll take CAS as the definitive call on this one. Thanks.--ChemSpiderMan (talk) 05:20, 10 January 2008 (UTC)
