[DCHAS-L] Conjugated picric acid hazards?

Demystify: 

Our biosafety officer is reviewing work that includes the use of a couple of forms of conjugated picric acid (TNP-AECM-FICOLL and TNP-Chicken Gamma Gobulin). The MSDS's are pretty skimpy, but include the advice to store it in a dessicated environment. This is counterintuitive to us and the MSDS's are vague enough about the material's reactivity ("Risk of explosion by mechanical impact: Not Available") that we'd like confirmation from people with more experience in the use of this material that picric acid's explosivity is not a concern in this application.

Does anyone on the list have more information about this concern?

Thanks for any help with this.
