Flamma® Fluors Dichlorotrazine
Flamma® Fluors dichlorotriazine is for labeling hydroxyl groups. Hydroxyls irreversibly displace one of chlorine at triazine ring via SNAr reaction pathway to yield an aryl ether linkage. Dichlorotriazines are among the few reactive groups that are reported to react directly with polysaccharides and other alcohols in aqueous solution, provided that the pH is >9 and other nucleophiles are not present.
