Why should we develop different methods for the separation of chiral compounds in pharmaceutical analysis?
Step by step
Solved in 2 steps
- The method of assay for sulfonamides is? Kjeldahl method Diazotization method Gravimetric analysis Titrimetric analysis Volumetric analysisWhat is asymmetric synthesis? write its application in medicinal chemistry?Describe with a suitable example why the characterisation of chiral compounds is important to the pharmaceutical industry and indicate why separation of the enantiomers can prove challenging. Explain how capillary electophoresis can be used in the analysis of these compounds.
- Predict whether the following complexes would show Jahn-Teller distortion: Ammonium pentachlorooxidochromate(V), meff = 1.8 mB Potassium hexaiodidomanganate(IV), meff = 3.8 mB Potassium hexachoridocuprate(II), meff = 1.8 mB Hexaaquamanganese(II) chloride, meff = 6.0 mBWhich is correct for polarography? I-polarography is an amperometry method conducted with a dripping Hg electrode. II-The diffusion current in the plateau region of the polarographic wave is proportional to the concentration of the analyte and is used for quantitative analysis. III-The half-wave potential is characteristic of the analyte in a given environment and can be used for qualitative analysis. IV-fresh Hg drops provide reproducible results. V-polarography is primarily used to study oxidations, Hg can be reduced when studying reductionsExplain the difference between resolution of optical isomers and racemization?
