Cholecalciferol, also known as Vitamin D3, is a fat-soluble vitamin essential for calcium absorption and bone health, widely used in pharmaceuticals, food fortification, and nutritional supplements. Beyond analytical work, cholecalciferol serves as the active ingredient in registered rodenticide products and in veterinary vitamin preparations, and as an inert ingredient in some non-food pesticide products. This certified reference standard is a high-purity analytical grade used for precise quantification and quality control in laboratories. CAS 67-97-0, molecular formula C27H44O with a molecular weight of 384.64 g/mol, it requires storage between 2 to 8°C. The product carries a signal word of *Danger* due to potential hazards. Molekula supplies Cholecalciferol (Certified Reference Standard) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
