The rapid synthesis of the non-steroidal anti-inflammatory agent Fenclofenac (2-(2,4-dichlorophenoxy)phenyl acetic acid) under microwave irradiation is reported. Modified reaction conditions of traditional Ullmann ether coupling resulted in high yields of the diaryl ether. The Willgerodt–Kindler transformation and subsequent hydrolysis of thioamide resulted in 52% overall yield of Fenclofenac.

Application Notes

This application note describes the fast extraction and quantitation of 10 different antidepressant drugs in urine using ISOLUTE SLE+ 1 mL columns.

Amitriptyline Clinical Clomipramine Column Desipramine Doxepin English Forensic Imipramine Nortryptiline Paroxetine Sertraline Tricyclic Antidepressant Trimipramine Urine

The screening of patient urine samples for basic drugs is typically performed following a lengthy sample preparation methodology that requires a time consuming dry down step. A novel elution protocol coupled to the EVOLUTE EXPRESS advanced plate technology affords a fast sample preparation solution that follows a LOAD-WASH-ELUTE-ANALYZE strategy. Basic drugs are fortified into urine and extracted in 3 easy steps using EVOLUTE EXPRESS CX solid phase extraction in a 96-well plate format.

This application note describes a method of extraction for metanephrine and normetanephrine from pooled plasma using EVOLUTE® EXPRESS WCX 96-well SPE plates. A new solid phase extraction technology has been developed to reduce the time associated with sample preparation methods by eliminating traditional steps in the extraction workflow. Leveraging this technology, a method protocol was developed using a load, wash and elute approach. This method was optimized for pooled plasma.

English Product Notes

Flash chromatography is the primary technology for separating, purifying, and isolating both synthetic organic compounds and natural products. Until recently, automated flash purification systems were limited to user-selected detection and collection wavelengths to fractionate separated compounds from sample mixtures. In this application note we demonstrate how the advances in Isolera Spektra are used in the purification of a spinach extract.

Application Notes

Isolera Spektra provides definitive fraction purity assessment in both 2-D and 3-D prior to any post flash analysis. With this information chemists quickly know if a fraction contains a pure product suitable for further mass and structure confirmation or whether the impure fractions must be re-purified. This knowledge improves synthesis throughput and avoids any embarrassment of submitting impure fractions for analytical evaluation.

Application Notes

The UV absorption spectrum of some solvents overlaps with the product they dissolve, meaning that fraction collection processes cannot distinguish between solvent and product. Luckily, there is technology that solves this problem.

Application Notes

Flash purification is a separation technique developed in 1978 by Professor W.C. Still that uses a stationary phase (a column or cartridge filled with an insoluble solid support) and a mobile phase (elution solvent mixture) to separate and purify a mixture of organic compounds.

Brochures

Elution of polar molecules in flash chromatography sometimes requires solvent additives, making purification more cumbersome. The Isolera™ family of flash purification instruments and Biotage® SNAP KP-NH cartridges significantly reduce the extra work involved.

Application Notes

Purify up to 400 grams of compound at 1 L/min with the Biotage Flash 150™ system, up to 2x faster than traditional glass columns. This robust stainless steel system safely operates at 100 psi enabling high flow rates and the use of higher viscosity solvents. A variety of cartridge media provides chemists with selectivity choices for optimal purification conditions. Simple and reliable, this system contains everything needed to begin your separations.
