Are DDO and DBDO available for sale there?
Thread Content
I’m going to conduct an analysis of Pt and Pb. But there is no dodecyl dithioethanediamide (DDO) nor dibenzyl dithioethanediamide (DBDO). I would like to ask where these two reagents can be purchased. It would be best if there were someone in the pool. Also request spectrally pure palladium wire and spectrally pure platinum wire.
I’ve been looking for a long time, but I still haven’t found it.
Let me tell you that the first two reagents may be available for order at some large reagent companies. But the latter two precious metals, especially platinum, are subject to controls, and you may need to apply for permission. You can also seek help from organizations that have such precious metal reagents. I have a platinum ring that I can sell to you at a reduced price. 1,000 yuan per gram; no price negotiation, no invoice provided. A prepayment of 3,000 yuan is required before discussing the transaction.
Using platinum jewelry as a standard sample is probably not appropriate. After all, the current price of 1 gram of platinum at 1,000 yuan seems quite high.
