The Fries rearrangement reaction is an organic name reaction which involves the conversion of phenolic esters into hydroxyaryl ketones on heating in the presence of a catalyst. Suitable catalysts for this reaction are Brønsted or Lewis acids such as HF
Knoevenagel Condensation is an organic reaction named after Emil Knoevenagel. It is a classic C-C bond formation reaction and a modification of the Aldol Condensation.
The aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872.
The Friedel–Crafts acylation is the reaction of an arene with acyl chlorides or anhydrides using a strong Lewis acid catalyst. This reaction proceeds via electrophilic aromatic substitution to form monoacylated products.
The Heck reaction is the palladium catalyzed cross-coupling reaction between alkenes and aryl or vinyl halides (or triflates) to afford substituted alkenes.
Novabiochem® product range has one of the largest collections of orthogonally and quasi-orthogonally protected tri-functional amino acids. These derivatives are useful tools for the synthesis of cyclic and branched peptides and peptides carrying side-chain modifications.
Acid and base chart lists the strength of acids and bases (strongest to weakest) in order. Simple to use laboratory reference chart for scientists, researchers and lab technicians.
Download the Periodic Table of the Elements with names, atomic mass and number in printable .pdf and image format. Use the periodic table chart by element names in alphabetical order for quick research, reference and lab use.
Use our handy VSEPR chart to find the 3-D geometric VSEPR shapes of molecules and ions. Learn about VSEPR theory and shapes like trigonal planar or square pyramidal. VSEPR stands for valence shell electron pair repulsion.
The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. Since the reaction involves the formation of a cyclic product via a cyclic transition state, it is also referred to as
The inverse electron demand Diels-Alder reactions of electron-deficient heterocycles are significant cycloaddition reactions for the total synthesis of natural products containing highly substituted and functionalized heteroaromatic ring systems.
Our Sure/Seal air-sensitive and anhydrous packaging system has been improved to incorporate larger puncture are and new elastomer liner which has greater sealing properties.
Pressure conversion table and chart. The pressure converter is ideal for converting atm to pa, bar to psi, kpa to atm, atm to torr and other common units. Quickly convert units of pressure in the lab, classroom or field.
As a versatile hydride reagent, 1-hydrosilatrane can be used in reduction reactions to synthesize alcohols, amines, their chiral counterparts, and esters from aldehydes/ketones.
The Biginelli Reaction is an acid-catalyzed, three-component reaction between an aldehyde, b-ketoester, and urea that produces tetrahydropyrimidones, which have potential pharmaceutical applications.
The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
PI and PSI reagents are a platform of phosphate-based reagents for phosphorylation and phosphothiolation of nucleotides and peptides developed by the Baran lab.
Unnatural amino acids, the non-proteinogenic amino acids that either occur naturally or are chemically synthesized, are becoming more and more important as tools for modern drug discovery research.
