The area logP is large, the accuracy is very high. But the area logP<0 the accuracy is not so high. In that area, emulsion happen and hard to separate. I always wonder why I can estimate logP with this simple group additivity method. I found the answer. When I was developing QSPR model to predict logP, I happened to plot logP vs molecular volume.
The chemical name of vanillin and ethyl vanillin are 4-hydroxy-3-methoxybenzaldehyde and 3-ethoxy-4-hydroxybenzaldehyd, respectively. In general, they are synergistically used to imitate vanilla: vanillin provides the characteristic vanilla flavor, and ethyl vanillin provides a creamy sweet flavor with vanilla notes.
Methyl salicylate is used in high concentrations as a rubefacient and analgesic in deep heating liniments (such as Bengay) to treat joint and muscular pain. Randomised double blind trials report that evidence of its effectiveness is weak, but stronger for acute pain than chronic pain, and that effectiveness may be due entirely to counterirritation.
O-glycans linked to the hydroxy amino acids Ser or Thr can be released by mild alkali treatment. This mild alkali treatment induces the β-elimination reaction, releasing O-linked carbohydrates from the β-carbon of Ser or Thr and leads to the formation of 2-aminopropenoic acid or 2-amino-2-butenocic acid, respectively ( Fig. 10.1 ).

This is why they are recognized as colors. Incidentally, the color that we see is the color that is not absorbed by the substance (which is called the “complementary color”). As shown in Fig. 4, New Coccine absorbs blue and green light in the range 450 to 550 nm, and so the complementary color, red, is seen by the human eye. Vanillin is the organic compound that gives vanilla its flavor, and is widely used in fragrances to impart gourmand sweetness. The chemical nature of vanillin leads it to cause a darkening or browning, especially of white products. This effect also occurs with natural vanilla extract.
