Strontium (Sr)
Named after a town in Scotland and isolated in 1808, strontium was recognized in 1790.
Strontium is softer than water and decomposes in it vigorously like calcium. The metal may ignite spontaneously in air, exposure to which rapidly changes the silvery appearance of its fresh surface to a yellowish hue. Strontium can be kept under kerosene to prevent oxidation.
A mixture of four stable isotopes forms natural strontium and sixteen unstable isotopes are also known to exist. Volatile strontium salts, which impart a crimson color to flame, are used in pyrotechnics and flares.
Found mostly in celestite and strontianite minerals, strontium can be used in medical imaging, ferrite magnet making, and zinc refining.

Strontium Ranelate is an antiosteoporotic agent that reduces bone resorption and promotes bone formation, leading to a positive bone balance. It activates the calcium-sensing receptor (CaSR) in non-skeletal cells, initiating inositol 1, 4, 5-triphosphate production and mitogen-activated protein kinase signaling. For research use only.
- Reduces bone resorption and promotes bone formation.
- Induces a positive bone balance.
- Activates calcium-sensing receptor (CaSR) in non-skeletal cells.
- Increases early and late osteoblast markers (ALP, OCN) in mouse calvaria cells in vitro.
- Increases alkaline phosphatase activity and prostaglandin E2 production.
- Increases bone mass in vertebrae and lumbar/femur in adult mice and rats in vivo.
- Decreases bone resorption and increases bone formation in alveolar bone.
- Prevents trabecular bone loss in ovariectomized rats, improving bone strength.
