The ability to determine which version of a chiral molecule is present in a substance is critical to the pharmaceutical industry. A classic example that had tragic results was thalidomide, a drug developed during the......found that combining all three methods together to generate a special composite adherence score proved more accurate than using each adherence measure by itself.
