Air & Water Reactions

3-ETHYLAMINOPHENOL may be sensitive to prolonged exposure to air. . Slightly soluble in water.

Reactivity Profile

An amine and phenol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Phenols do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.

Flash point data for 3-ETHYLAMINOPHENOL are not available, however, 3-ETHYLAMINOPHENOL is probably combustible.

Structural modifications of nile red carbon monoxide fluorescent probe: Sensing mechanism and applications

Carbon monoxide (CO) is a cell-signaling molecule (gasotransmitter) produced endogenously by oxidative catabolism of heme, and the understanding of its spatial and temporal sensing at the cellular level is still an open challenge. Synthesis, optical properties, and study of the sensing mechanism of Nile red Pd-based CO chemosensors, structurally modified by core and bridge substituents, in methanol and aqueous solutions are reported in this work. The sensing fluorescence "off-on" response of palladacycle-based sensors possessing low-background fluorescence arises from their reaction with CO to release the corresponding highly fluorescent Nile red derivatives in the final step. Our mechanistic study showed that electron-withdrawing and electron-donating core substituents affect the rate-determining step of the reaction. More importantly, the substituents were found to have a substantial effect on the Nile red sensor fluorescence quantum yields, hereby defining the sensing detection limit. The highest overall fluorescence and sensing rate enhancements were found for a 2-hydroxy palladacycle derivative, which was used in subsequent biological studies on mouse hepatoma cells as it easily crosses the cell membrane and qualitatively traces the localization of CO within the intracellular compartment with the linear quantitative response to increasing CO concentrations.

Acrylamide-Coumarin-Benzaldehyde as a Turn-on Fluorescent Probe Providing an Enhanced Water Solubility for Detection of Cysteine and Homocysteine

We presented an acrylamide conjugated coumarin (1) as a fluorescent probe for detection of cysteine (Cys) and homocysteine (Hcy). Probe 1 is composed of coumarin as a fluorophore, acrylamide as a reactive site to Cys/Hcy, and benzaldehyde for improvement of the water solubility. To Cys/Hcy, the acrylamide group of 1 readily undergoes Michael addition resulting in a strong fluorescence at 420 nm through an inhibition of photo-induced electron transfer (PET). The turn-on fluorescence change of 1 was observed for Cys and Hcy, but not seen for other biologically abundant thiols (e.g., glutathione, H2S), reactive oxygen and nitrogen species, anions, and metal ions. Moreover, 1 can give strong fluorescence upon the addition of Cys and Hcy in wide pH range and their limits of detection for Cys and Hcy turned out to be 17.25 and 8.69 μM, respectively.

Tuning thiol addition to squaraines by ortho-substitution and the use of serum albumin

Tuning the reactivity of squaraine dyes toward nucleophilic addition of thiols was investigated. A series of water soluble, aniline-derived squaraines were synthesized with various ortho substitutions to the squaraine ring. As hypothesized, we found that placing moderately electron donating groups in the ortho position conveyed intermediate reactivity to thiols between the essentially non-reactive hydroxyl-substituted squaraines and very reactive non-substituted squaraines. Furthermore, serum albumin was tested for its influence on the addition of thiols to the squaraines. The dyes bind in the hydrophobic cavities of the protein, and thus we expected serum albumin to affect the squaraines' reactivity. Rather than a protective effect by the protein, we found a cooperative effect for thiol addition.

Synthesis and photophysical studies of new benzo[a]phenoxazinium chlorides as potential antifungal agents

A set of four new benzo[a]phenoxazinium chlorides possessing ethyl, propyl, decyl and tetradecyl groups at the 9-amino function of the heterocycle along with a propyl group at the 5-amino position was efficiently synthesized. These compounds displayed fluorescence with maximum emission wavelengths of 673 and 685?nm, in anhydrous ethanol and water. All the benzo[a]phenoxazines were evaluated against the yeast Saccharomyces cerevisiae in a broth microdilution assay. It was found that their antifungal activity depended on the variation in the lengths of the aliphatic chains. The highest MIC activity of 1.56?μM was obtained for compound 7 comprising a di-alkylated propyl substituent at 9-amino position and a propyl chain at the 5-amino position of the heterocycle core.
