1,700+ technical articles by Aladdin Scientific's scientists on reagent selection, reaction mechanisms, assay design and formulation. New every week.
Neurons are central nervous system (CNS) cells that receive and transmit electrochemical signals through a process called neurotransmission. The anatomy of neurons is designed to receive and send messages from neighboring cells. The axonal burst sends signals, and the dendrites receive messages ...
Hydrogenation is a very common reaction in which H2 can be introduced through double or triple bonds and is widely used in both laboratory and industrial production. This reaction usually requires the presence of metal catalysts in order to carry out, in the presence of such catalysts, it is ...
The photoreaction undergoes a special molecular transformation to form a product that is not obtained through a thermal reaction. In recent years, the light reaction induced by visible light has been further developed. The light reaction in visible light does not require high-energy ultraviolet ...
Traditional vaccines can be divided into four types: live attenuated vaccines, inactivated vaccines, subunit vaccines, recombinant vaccines, polysaccharide and conjugate vaccines, and toxoid vaccines. While many of these vaccines play an important role in controlling infectious diseases, some ...
In organic chemistry, Markovnikov's rule or Markownikoff's rule describes the results of an addition reaction, also known as a halogenation reaction (under standard conditions), carried out after the addition of the protonic acid HX or other polar reagents to an asymmetric olefin. It was first ...
Small-molecule drugs are variable-specificity drugs targeted within cells, typically well-defined organic substances with a molecular weight of fewer than 900 Daltons, that help regulate biological processes. Due to differences in size, manufacturing, pharmacokinetics, pharmacodynamics, and ...
Aladdin offers the isothiourea organocatalyst homobenzotetramisole (HBTM) as part of our asymmetric catalysis portfolio in both (R, item number: B120975) and (S, item number: B120963) enantiomeric forms. These compounds have been widely used for enantioselective conversion and kinetic resolution ...
Over the past few decades, magnetic nanoparticles (MNPs) have been increasingly used to separate and differentiate biomolecules, which is the basis of most current molecular diagnostic procedures. The size, morphology, and dispersion of MNPs endow them with specificity, affinity, and binding ...
Although the Markovian rule plays a key role in explaining the mechanism of olefin Addition reaction, and it has also been widely used in scientific research and practical production, there are very few kinds of addition products with anti Markovian rules obtained through catalytic processes.
