N-(4-Nitrophenyl)-D-glucopyranosylamine is a conjugate that is used in food testing, environmental testing, and diagnostics. It is a fluorogenic substrate that reacts with the enzyme glucose oxidase to produce a yellow color. This product has high purity and quality and CAS No. 553-03-6. It also has bioluminescence properties.

2-Nitrophenyl 2-acetamido-3,6-di-O-acetyl-4-O-[2-O-(2,3,4-tri-O-benzoyl-a-L-fucopyranosyl)]--2-deoxy--bDglucopyranoside is an acylated glucopyranoside that is used as a substrate for the enzyme β -galactosidase. When hydrolyzed by β -galactosidase, it yields a blue product that has been widely used in chemiluminescence and bioluminescence assays. It also can be used for staining and ligand binding studies.

5-Bromo-6-chloro-3-indolyl palmitate is a magenta enzyme substrate that is widely used in the study of lipase and esterase enzymes. This compound consists of an indole ring with bromine and chlorine atoms at positions 5 and 6, respectively, and a palmitate moiety esterified to the indolyl ring. The palmitate group is a long-chain fatty acid, making this substrate particularly useful for investigating enzymes that hydrolyze ester bonds in lipids. Upon cleavage by lipases or esterases, 5-Bromo-6-chloro-3-indolyl palmitate releases a magenta-colored product, which can be easily detected and quantified to measure enzyme activity.

6-Bromo-2-naphthyl-alpha-D-mannopyranoside is a strong inhibitor of alpha-mannosidase. It has been shown to inhibit the growth of Mycobacterium tuberculosis and Streptococcus pneumoniae, which are both known to cause bacterial infections in humans. 6BNA inhibits the enzyme alpha-mannosidase, which hydrolyzes terminal α-(1,4)-linked mannose residues from oligosaccharides and glycoproteins. This drug has a high affinity for the active site of alpha-mannosidase and an IC50 value of 0.2 mM, making it an effective inhibitor.
