General description
Strontium chloride hexahydrate (SrCl2·6H2O) is a hydrated alkaline earth metal chloride. On γ-irradiation at 77°K, it affords a radical having e.s.r. parameters resembling with HO2. Its chlorine electric field gradient (EFG) and chemical shift (CS) tensors have been evaluated by employing solid-state 35/37Cl NMR spectroscopy.
Application
Strontium chloride hexahydrate (SrCl2·6H2O) may be employed as a catalyst for the synthesis of gem-dihydroperoxides (DHPs) from aldehydes or ketones.It may be used for the preparation of SrCl2·2H2O.

Emerging evidence suggests comprehensive immune profiling represents a highly promising, yet insufficiently tapped approach to identify potentially prognostic signatures for periodontitis. In this report, we agnostically identified a periodontitis-associated inflammatory expression network with multiple biomarkers identified within gingival crevicular fluid
