Where to order FOA? - (Oct/08/2009 )

Hi everybody!

I need to purchase several grams of 5-FOA. We've ordered it from Sigma in the past and it's ridiculously expensive ($500/g). I've been looking around and I found that RPI has it for $50/g. Has anyone had problems with RPI's chemicals? Why are they soooooo much cheaper? Or is Sigma just extremely overpriced?

Thanks!

Sigma is one of the biggest and best chemical suppliers in the world... I suspect that the other company has lesser quality product (purity, concentration, stability) or a typo on their webpage.
