Usage

General Description

4-Butylbenzyl Bromide, also known as Benzyl Bromide, is a clear, colorless organic compound with a strong lachrymatory effect - meaning it can cause tears or crying due to its irritant properties. It belongs to the class of organic compounds known as benzyl bromides, specifically, an organic aryl halide where the aryl group indicated is phenyl substituted at one carbon with a butyl group and a bromine atom. Being highly reactive, it can be used as a precursor for the synthesis of other chemical compounds. It can often be found in laboratories and industries dealing with chemical production. However, due to its highly corrosive nature, it can lead to severe burns and eye damage, therefore, it must be handled with extreme caution.

Surfactant and Hydrophobic Derivatives of trans-Stilbenes as Probes of Vesicle and Micelle Solubilization Sites. Studies Using Fluorescence and Photoisomerization as Probes

An investigation of the fluorescence and photoisomerization of several surfactant trans-stilbene derivatives in aqueous micelles and vesicles is reported.The temperature dependence of Φf was determined for several media over the range 5-70 deg C.The results present a picture of similar micellar solubilization sites for the trans-stilbene chromophore in every case; the micelle is "seen" by the stilbene as a moderately viscous fluid medium with slightly higher values for Φf and slightly reduced Φt->c compared to nonviscous homogeneous solutions.For vesicles considerably more complex behavior is observed.Generally Φf is considerably higher than in solution and Φt->c is much lower.Several, but not all, of the surfactant and hydrophobic stilbenes show a sharp sensitivity in Φf as a function of T when passing through Tc, the vesicle phase transition temperature.Arrhenius plots for the process competing with fluorescence as a function of temperature show relatively high values for Ea and log A, above Tc, consistent with the high temperature phase providing a microenvironment for the stilbene chromophore like a viscous solvent.Below Tc, the variation of Φf gives much lower values for EA and log A which suggest escape from the fluorescence state is "order limited" rather than viscosity dominated.These results suggest that the low-temperature phase of vesicles presents an environment for the stilbene chromophore more like an inclusion complex than a fluid medium.The effect of cholesterol addition on DODAC vesicles containing the stilbenes is to increase fluidity below Tc and to effectively increase viscosity above Tc.

Odorless substitutes for foul-smelling thiols: Syntheses and applications

Several alkanethiols and p-alkylphenylmethanethiols were synthesized, and their odors were compared with those of ethanethiol and benzyl mercaptan by human and instrumental sensors. Among the various thiols analyzed, 1-dodecanethiol (1) and p-heptylphenylmethanethiol (3) were revealed to be odorless. 1-Dodecanethiol (1) has been used instead of ethanethiol for dealkylation of ethers, and p-heptylphenylmethanethiol (3) can replace benzyl mercaptan in the preparation of a 1,3-mercapto alcohol from an α,β-unsaturated ketone. These odorless thiols will greatly improve the physical environment of the researcher working with these foul-smelling compounds.
