6-Chloro-3-indolyl 2-acetamido-2-deoxy-b-D-glucopyranoside is a pink enzyme substrate commonly used in biochemical research and diagnostic applications. This compound is a derivative of indolyl glucopyranoside, which is known for its ability to produce a colored product upon enzymatic hydrolysis. 6-Chloro-3-indolyl 2-acetamido-2-deoxy-b-D-glucopyranoside is particularly useful for studying glycosidases, enzymes that cleave glycosidic bonds in complex carbohydrates. Its pink coloration makes it an ideal choice for colorimetric assays, enabling researchers to monitor enzyme activity in real-time and facilitating the development of new diagnostic tools and therapeutic strategies.

6-Chloro-3-indolyl 2-acetamido-2-deoxy-b-D-galactopyranoside is a chromogenic substrate for N-acetyl-beta-galactosaminidase. It produces a salmon-pink color after enzymatic cleavage.

Chromogenic substrate for esterase with C9 activity yielding a salmon colored precipitate upon cleavage.

5-Bromo-4-chloro-3-indoxyl-1-acetate is a chromogenic substrate used to detect the specific enzymatic activity of esterase. After cleavage, 5-bromo-4-chloro-indoxyl is released, resulting in a blue to blue-green color change in bacterial colonies or media. 5-Bromo-4-chloro-3-indoxyl-1-acetate is used in bacterial esterase activity assays (e.g. Pseudomonas spp.).

5-Bromo-3-indolyl phosphate disodium salt is a chemiluminescent substrate that is used for the detection of bacterial activity. It reacts with oxygen to produce light, which can be measured using a luminometer. It is also used as a chromogenic substrate for detection of bacterial activity in culture media. The enzyme reaction produces an intense blue fluorescence and is used for diagnostic purposes in food testing and medical diagnostics. 5-Bromo-3-indolyl phosphate disodium salt has been shown to be effective against many bacteria and fungi, including Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. This product is chemically stable at room temperature but should be stored at 4°C or below.

Aldol 458 nonanoate is a fluorogenic substrate that can be used in the detection of enzyme activity particularly C8/C9-esterases, lipases activity producing a yellow/green-orange color. Aldol 458 nonanoate reacts with enzymes, such as oxidoreductases and hydrolases, to produce light. This product is a conjugate of aldol 458 nonanoate and an enzyme substrate for the detection of these enzymes. It has been shown to be useful in food testing, staining, fluorogenic substrate, environmental testing, chromogenic substrate, conjugate, high purity, enzyme substrate for diagnostics and ligand.
