Usage

General Description

Azobenzene-4-yl isocyanate is a chemical compound with the molecular formula C14H9N3O. It is a highly reactive and potentially hazardous compound commonly used in organic synthesis and chemical research. Azobenzene-4-yl isocyanate is classified as an isocyanate, which are known to be potent respiratory and skin irritants. Exposure to this compound can cause irritation to the eyes, skin, and respiratory tract. In addition, prolonged or repeated exposure may cause sensitization and allergic reactions. Therefore, proper handling, storage, and use of azobenzene-4-yl isocyanate are essential to minimize potential health risks.

Visible colorimetric fluoride ion sensors

(Chemical Equation Presented) Five new urea derivative naphthalene compounds were synthesized by a reaction of 1,8-diaminonaphthalene and the corresponding isocyanates and showed a distinct color change only when treated with fluoride ions.

Development of a photoswitchable antagonist of NMDA receptors

N-methyl–Daspartate receptors (NMDARs) are vital for neurological processes such as learning, memory, and synaptic plasticity. As such, small molecules that modulate their function are of interest in the study of numerous neurological diseases. We have synthesized a small library of photoswitches that modulate NMDAR function. The most efficient photoswitch to date is based on a known ligand of the glycine binding site and shows significant subtype selectivity.
