Propargyl-PEG8-amine is a heterobifunctional reagent consisting of a propargyl group and an amine group. The amine group can form amide bonds with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl group can form triazole linkage with azides in copper catalyzed Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The Benzoic Acid Detection Kit provides a rapid, simple, sensitive, and reliable test suitable for screening of Benzoic Acid concentration.
Benzoic Acid is a white solid that is an extensively used preservative. Although this preservative prevents or delays nutritional losses due to microbiological, enzymatic or chemical changes of foods during its shelf life there is a suspicion that small amounts of benzene may be formed from benzoic acid in nonalcoholic beverages in the presence of ascorbic acid. Benzoic acid and ascorbic acid are food additives which must be declared on the food. Benzoic acid or E 210 is a preservative which also occurs naturally, for instance, in cranberries. A maximum amount of 150 mg/l benzoic acid may be added to non-alcoholic flavored beverages.
