Cat. No.: HY-W129633
CAS No.: 1266615-56-8
Synonyms: DCIP sodium hydrate; DPIP sodium hydrate
2,6-Dichlorophenolindophenol (DCIP; DPIP) sodium hydrate is a redox chromogenic indicator with a redox potential of +217 mV relative to SHE, and it acts as a substrate for reduction reactions. During the metabolic process of nutrient consumption by Saccharomyces cerevisiae, 2,6-Dichlorophenolindophenol sodium hydrate is reduced from dark blue to colorless, resulting in a decrease in absorbance. 2,6-Dichlorophenolindophenol sodium hydrate is widely used in spectrophotometric biochemical oxygen demand determination and preclinical colorimetric toxicity analysis for heavy metal ion detection based on Saccharomyces cerevisiae .

1 Cited Publications
Cat. No.: HY-W110883
CAS No.: 3618-43-7
Xylenol orange tetrasodium salt, IND is commonly used as a colorimetric indicator for metal titration and possesses Zn 2+ chelating activity. Xylenol orange tetrasodium salt, IND binds Zn 2+ under physiological pH, and its Zn-XO complex allows visual differentiation between tartrate and malate ions. Xylenol orange tetrasodium salt, IND undergoes decolorization upon oxidation by hydrogen peroxide, undergoes a Co (II)-catalyzed pseudo-second-order reaction in a strong alkaline environment, and regulates the ferrous ion oxidation process mediated by peroxy radicals. Xylenol orange tetrasodium salt, IND forms colored ternary complexes with various anions, cations and iron-alanine, which is suitable for spectrophotometric quantification and can also be used for alanine irradiation dose detection. Xylenol orange tetrasodium salt, IND is applicable to EDTA metal titration analysis under acidic conditions .

Cat. No.: HY-Y0699
CAS No.: 493-52-7
Methyl red is a pH-sensitive acid-base indicator and colorimetric reagent with a pKa of 5.1. Methyl red achieves visual judgment of the titration endpoint through reversible structural changes of protonation (red, pH < 4.4) and deprotonation (yellow, pH > 6.2). Methyl red is widely used in acid-base titration in chemical analysis and buffer pH monitoring in biochemistry .

CAS No.: 2361979-91-9
NRh-Cu is a highly sensitive near-infrared fluorescence turn-on indicator and Cu 2+-selective probe (λex=680 nm, λem=740 nm). When NRh-Cu interacts with Cu 2+, it undergoes a structural transition from a non-fluorescent spirocyclic state to a fluorescent ring-opened state, which drives the enhancement of fluorescence emission. NRh-Cu can be used for Cu 2+ imaging in live cells and in vivo .
