N-(Amino-PEG1)-N-bis(PEG2-propargyl) HCl salt is a crosslinker consisting of an amino group with two propargyl groups. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. 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.
Highly Sensitive Assay to Screen for Benzoic Acid
Visual Readout (sample dependent: milk, red/pink)
Detection range of 1ppm to 1500ppm
Tube or Plate based options available
Compatible with the Nix Sensor or plate readers to obtain quantitative results.
DBCO-PEG4-PC represents a photocleavable, PEG linker consisting of a DBCO group that can be used for copper-free Click Chemistry reactions. This structure allows for efficient photorelease of linked molecules, typically achieving over 90% cleavage in 5-25 minutes using a near-UV lamp. The PEG4 spacer increases the hydrophilicity of the compound.
