   Dear Tom,

   We need 2,6-Anthracenedisulfonicacid, 1,4-diamino-9,10-dihydro-9,10-dioxo-, sodium salt (1:2), CAS No.: 6408-69-1. If you have the compound please let us know lead time and price for 150g, 500g and 2,000g for delivery to Beijing, China.

   Please note we need analytical evidence of product quality before we order. This might include NMR and LC-MS. If you do not have data to prove the structure we need a small sample so that we can carry out full analysis in our laboratory in Beijing.

   I look forward to hearing from you soon.
