For small numbers of molecules, time evolution for a CRN is described by the chemical master equation: this says how the probability of having any number of molecules of each given species changes with time.  A very similar formalism appears in quantum mechanics, but with 'complex amplitudes' replacing nonnegative real probabilities.  As a result, we can take techniques from quantum mechanics and use them to give new proofs of results in CRN theory:

Conversely, we can take ideas from CRN theory and see if they apply to quantum mechanics.
