The structure of the compound using given spectroscopic data is to be elucidated. Concept introduction: NMR data indicates the number and type of protons or carbons present in a compound based on the number of signals obtained in 1 H NMR or 13 C NMR respectively. 1 H NMR signals are often indicated as mutiplet such as doublet, triplets, which indicates the number of protons present on carbons adjacent to that proton. Protons of aromatic rings show signals from 6.5 to 7.5 ppm , those of alkyl group from 0.5 to 1.5 ppm , while alkyl groups adjacent to a carbonyl group or oxygen atom show signals from 2.0 to 3.0 ppm . Alcohol groups show a signal at 2.0 to 3.0 ppm but are always a singlet. Mass spectra of a compound indicate the molecular ion peak which gives the molecular mass of the compound.

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
