Etidronate (Cat No.: R000103) is a first generation, non-nitrogenous diphosphonate analog of endogenous pyrophosphate. It binds to hydroxyapatite and induces osteoclast apoptosis, thereby inhibiting abnormal bone resorption. Unlike other bisphosphonates, etidronate may also prevent bone calcification. Additionally, it is used in cleaning agents, detergents, and cosmetics for its ability to stabilize formulations and enhance efficacy. The compound also finds applications in agriculture, acting as an effective growth enhancer and pesticide.
