**3.4 Stability of molecule**

The main objective of determining stability of molecule is to identify the conditions in which molecule is susceptible to deteriorate and to determine degradation pathway. The mechanism of degradation and condition provides the idea about proper designing of formulation, suitable molecular modification, appropriate storage condition, and selection of proper packaging material.


**Table 1.** *Advantage of racemic switching.*

The major mechanisms by which a molecule undergoes degradation are hydrolysis, oxidation, photolysis, and racemization. Out of these mechanisms, hydrolysis is perhaps the most studied after oxidation.
