Iscove's Modified Dulbecco's Media (IMDM) Formulation

Reducing Organic Photoredox Catalysts for Visible Light-Driven Polymer and Small Molecule Synthesis

Photoredox catalysis is a powerful synthetic methodology to form challenging covalent bonds using light irradiation. It is effective for light-driven polymer and small molecule synthesis.

Biginelli Reaction

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.

Sure/Seal™ Packaging System

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.

C-O Cross-Coupling of Activated Aryl and Heteroaryl Halides with Aliphatic Alcohols

JosiPhos CyPF-tBu and palladium give catalyst for alkoxylation of activated heteroaryl halides with primary, secondary, and tertiary alcohols

N-Heterocyclic Carbene (NHC) Ligands

Emerging class of privileged ligands

Rovis Triazolium Catalyst

Rovis has demonstrated that triazolium salt in the presence of a base can act as an N-heterocyclic carbene organocatalyst in highly enantioselective intramolecular Stetter reactions.

Aminophosphine Ligands

KitAlysis™ C-N (Buchwald-Hartwig) High-Throughput Screening Kit

All contents in the foil bag are weighed, plated, packed, and sealed in a glove box under nitrogen.

DIOP for Asymmetric Hydrogenation Catalysis

DIOP

MRT - Mono-Boc-Protection of Diamines

Mono-Boc-protected diamines are versatile building blocks for chemical synthesis. Their production is a lot more challenging than the simple reaction scheme might imply, because the Boc-anhydride reagent cannot differentiate between the two identical amino moieties in the substrate.

Nok – Third-Generation Amphiphile for Cross-Coupling Chemistry in Water

Micellular catalysis has provided the ability to carry out several commonly used transformations used in the synthetic community to be carried out in water.

Catalysts for Carbonylation

Professor Geoffrey Coates and co-workers at Cornell University have reported the preparation and use of catalysts composed of an oxophilic Lewis acid and a cobalt tetracarbonyl anion for the ring expansive carbonylation of epoxides to b-lactones and b-lactones to succinic

Asymmetric Transfer Hydrogenation

Organic Azides and Azide Sources

Since the preparation of the first organic azide, phenyl azide, by Peter Griess in 1864 this energy-rich and versatile class of compounds has enjoyed considerable interest.

Lithium Aminoborohydride (LAB) Reagents

Lithium aminoborohydride (LAB) reagents are a new class of powerful and selective reagents developed in the laboratory of Professor Bakthan Singaram at the University of California, Santa Cruz.

Mild Mg – Halogen Exchange

Substantial progress has been made in magnesium–halogen exchange reactions used for the preparation of functionalized Grignard reagents containing sensitive moieties such as ester or cyano groups.

BINAP/SEGPHOS® Ligands and Complexes

We present an article concerning BINAP/SEGPHOS® Ligands and Complexes.

Trichloroacetimidate Reagents

Trichloroacetimidates are also commonly employed as alcohol alkylation reagents, particularly when existing functionality is not acid sensitive.

Benefits of Ascentis Express Phenyl-Hexyl over Biphenyl for the Separation of Pain Management Opiates

Although both biphenyl and phenyl-hexyl phases can resolve these compounds, the former exhibits excellent peak shape and substantially less silanol-derived ion exchange activity.

Ultra-High Performance Liquid Chromatography (UHPLC) with the Ascentis® Express Phenyl-Hexyl Column

Bioanalysis with SPME

Biocompatible SPME devices employ C18 bonded porous silica sorbent particles, in a binder which resists fouling by biological matrix components

Traceable Organic Certified Reference Materials for P-31 qNMR

The use of CRMs for the NMR quantification of phosphorylated organic compounds and metabolites offers several advantages as it is based on a signal comparison of the analyte with an internal or external reference standard.

Two Distinct Sample Prep Approaches to Overcome Matrix Effect in LC/MS of Serum or Plasma Samples

This article highlights the impact that sample matrix effects can have on LC/MS response and discusses two novel approaches to reduce it.

Reference Standards for Analyzing Polyphenol Catechins

Determination of Stevioside and Rebaudioside A in Stevia leaves, beverages and food additives using HPTLC-MS

HPTLC-MS was used to analyze stevioside and rebaudioside in artificial sweeteners, stevia plants, cola and isotonic drinks with a minimum of sample preparation.
