They are quite stable:

Front. Plant Sci., 26 August 2014 | https://doi.org/10.3389/fpls.2014.00417

Nagarajan Krishnan

In -20C, Most of the chemicals are stable. It will be a frozen state. No possibilities of reaction, also no possibilities of interacting with atmospheric oxygen or any other. That's why we are storing the blood samples or stem cells or any samples that we are going to analyze, need to store in low temperatures like -20C or we can go up to -70C. It will be very stable.
