Chiral gas
WebChiral drugs that are equimolar (1:1) mixture of enantiomers are called racemic drugs and these are obviously devoid of optical rotation. The most commonly encountered stereogenic unit, that confers chirality to drug molecules are stereogenic center. Stereogenic center can be due to the presence of tetrahedral tetra coordinate atoms (C,N,P) and ... WebChiral chromatography is typically performed in classical elution mode. A mobile phase is continuously passed through a column containing a stationary phase (Figure 7(A)). The …
