Hi guys
I already bought a Oleylamine of Sigma-aldrich 07805 (cas num: 112-90-3). this was colorless and as the glue was very viscose. But new oleylamine that I prepare, don't has the same appearance and now it has color like beige. Also the seller claim that their products is original. So I don't know which one is the right form of Oleylamine. Do any one have experience about this?
Thanks in advance
