These include thallium, polonium 210 (a radioactive substance of which a few milligrams are lethal), nerium oleander, snake venom, photolabile
poisons and heroin.
Unfortunately, a corollary of this property is that some E vitamins are photolabile
and are subject to photodegradation .
1979), had a photolabile

Their topics include cyclative cleavage as a solid-phase strategy, photolabile
linker units, hydrazone linker units, diversity cleavage strategies from phosphorus linkers, silicon and germanium linker units, linkers releasing olefins or cyclo-olefins by ring closing metathesis, and solid-phase radiochemistry.

ligands have been investigated for drug discovery (Dorman and Prestwich, 2000).
The presence of carbonyl groups in a degraded polymer indicates that oxidation has occurred and that the material is vulnerable to further degradation because these groups are photolabile
To eliminate interference from nonbilirubin pigments, my colleagues and I (2) exploited the fact that bilirubin is highly photolabile
whereas interfering chromagens such as hemoglobin and methemoglobin are remarkably photostable.
Those indoxyls, which have substituents in the 2-position, are oxidized to indoleninones that dimerise to give the green photolabile
Masscode tags have a modular structure, including a tetrafluorophenyl ester for tag conjugation to primary amines; an o-nitrobenzyl photolabile
linker for photoredox cleavage of the tag from the analyte; a mass spectrometry sensitivity enhancer, which improves the efficiency of atmospheric pressure chemical ionization of the cleaved tag; and a variable mass unit for variation of the cleaved tag mass (8,10-12).
Thin-film composite membranes are fabricated by the interfacial polymerization of monomers on the surface of a porous support membrane; including a photolabile
mobile group in one of the membranes allows subsequent modification of the membrane surface properties, hence influencing membrane performance flux and separation).
