Cat. No.: HY-W011422
CAS No.: 537-45-1
Synonyms: NSC 528
2,6-Dibromo-4-(chloroimino)cyclohexa-2,5-dienone (NSC 528) is a colorimetric dye used for the detection of phenolic compounds. 2,6-Dibromo-4-(chloroimino)cyclohexa-2,5-dienone reacts with phenolic compounds at a pH of about 9.4 to produce an indigo dye. 2,6-Dibromo-4-(chloroimino)cyclohexa-2,5-dienone has been used as a Gibbs reagent for the colorimetric detection of phenolic compounds. 2,6-Dibromo-4-(chloroimino)cyclohexa-2,5-dienone has also been used in a colorimetric reaction for the quantitative colorimetric detection of aflatoxins, turning the colorless aflatoxins green with an absorption band at 673 nm.

Cat. No.: HY-W009458
CAS No.: 3318-43-2
Synonyms: 3-IP sodium
3-Indoxyl phosphate (3-IP) is a chromogenic and electrochemical substrate for alkaline phosphatase. Upon enzymatic cleavage by alkaline phosphatase, 3-indoxyl is released and subsequently oxidized to produce water-insoluble indigo, which can be quantified by colorimetric detection at 660 nm as a measure of alkaline phosphatase activity. 3-Indoxyl phosphate can also be converted to water-soluble leucoindigo by reduction of indigo in alkaline solution by sodium dithionite, which can be quantified by colorimetric detection at 415 nm or voltametric detection as a measure of alkaline phosphatase activity.2 3-Indoxyl phosphate has been used in ELISAs.

FAHF is a polypeptide-based dual-signal fluorescent colorimetric probe synthesized by conjugating the 5-carboxyfluorescein (5-FAM) (HY-66022) fluorophore to the Ala-His-Phe-NH2 tripeptide backbone. FAHF achieves highly selective recognition of Cu 2+ via fluorescence quenching and colorimetric change. The FAHF-Cu 2+ complex responds to Glyphosate (HY-B0863) based on the displacement effect, resulting in fluorescence enhancement and a visually distinguishable color change. FAHF can penetrate cell membranes to enable cascade detection of copper (II) and glyphosate in living cells, and it can also be combined with smartphone RGB analysis for semi-quantitative identification .

RDDB is a rhodamine-based turn-on fluorescent and colorimetric chemosensor selective for Mn 2+, with a limit of detection of 5×10 -8 M (excitation wavelength: 480-550 nm; fluorescence signal collection range: >590 nm). In the presence of Mn 2+, RDDB undergoes a spirolactam ring-opening reaction of its rhodamine hydrazide moiety, resulting in turn-on fluorescence and a color change. RDDB can be used for intracellular Mn 2+ imaging .

Ehrlich's Reagent is an indicator with p-dimethylaminobenzaldehyde (HY-Y0015) as its core component. Ehrlich's Reagent is mainly used for the identification of enterobacteria, non-fermentative bacteria, fastidious bacteria and anaerobic bacteria, as well as the detection of indole derivatives and amines. It turns pink, red or purple when a positive reaction occurs. Ehrlich's Reagent undergoes colorimetric reactions with urobilinogen, indican, phenol, allantoin, tryptophan and uric acid, and forms yellow-green products when reacting with sulfur derivatives .
