To reconstitute, dissolve the Alexa Fluor carboxylic acid compound in aqueous buffer (e.g. PBS), or high-quality, anhydrous dimethylsulfoxide (DMSO) or dimethylformamide (DMF) at a final concentration of 1–10 mg/mL. Once reconstituted, this solution is stable for 1 year, when stored at 2...
an alkanol such as methanol, ethanol, propanol, isopropanol, butanol, acetone, methyl ethyl ketone, acetonitrile, DMF, DMSO. The alkanol portion amounts to about 10 to 90, or 20 to 70, advantageously 30 to 50% by volume. For higher alkanols, the less polar solvent may also be present ...
The reported reaction proceeds mildly in a single step without the need of a previous isolation of the free amine from its salt. N,N-Dimethylformamide (DMF) is used as the solvent and TiCl4 as the drying agent.M. SelvaDipartimento di ScienzeP. Tundo & C. A. Marques...
Anhydrous MeOAc (1.6 mL) and anhydrous DMF (0.4 mL) were then added via a syringe, followed by the addition of an alkyl bromide (0.2 mmol, 1.0 equiv) and tris(trimethylsilyl)silanol (95 µL, 0.3 mmol, 1.5 equiv). The vial was sealed and removed from the glovebox. ...
All polymers were prepared under similar conditions. The following procedure illustrates the method used. Into a 1 L three-necked flask equipped with a heating mantle, reflux condensor, overhead stirrer, and nitrogen inlet was added 130 ml of DMF, 130 ml of MeOH, 46.4 g (0.40 mole) of he...
When a mixture containing 1‐halo‐1‐alkyne, a dinucleophilic agent, and a base (Cs2CO3 or K3PO4) was heated in DMF, regio‐ and stereo‐selective nucleop... T Hata,Y Tatsumi,Y Kanai,... - 《Advanced Synthesis & Catalysis》 被引量: 0发表: 2024年 AM真菌菌丝际细菌具有固氮解磷双重...
the naked aryl anion is not believed to be formed in the arylation process. Carbon dioxide cannot be detected by GC–MS in the gas phase of the reaction system because the gas phase was full of the solvent THF. Fortunately, when DMF was used instead of THF in the reaction of aldehyde1a...

To a 25 mL oven-dried pressure tube equipped with a magnetic stir bar were added difluoroallyl ammonium salt1(0.36 mmol), NaH (0.45 mmol), DMF (1.5 mL), and then nucleophiles2(0.3 mmol) was introduced under argon atmosphere. The sealed pressure tube was vigorously stirred...
(I) by mixing neutral, aqueous alkali sulphinate solutions of formula MO2S-CH(CH2R')(CH2SO3M) (III) with alkylating agents of formula R-X (IV; with X = halogen, e.g. Cl, Br or I) in dimethylformamide (DMF) and optionally with catalytic amounts of alkali iodide, and heating ...
