CAS 9000-71-9 — Casein from bovine milk

Casein from bovine milk is a family of related phosphoproteins derived from cow’s milk, widely used in food, pharmaceuticals, and biotechnology as an emulsifier, protein supplement, and nutrient delivery agent. It appears as a white to light yellow powder, insoluble in water but dispersible in acidic or alkaline solutions. This product has a CAS number of 9000-71-9, with a variable molecular composition (not strictly C₁₀H₁₀Cr₂N₂O₇—this appears to be incorrect; casein’s structure is complex and not defined by a single formula). It is stored at ambient conditions, carries no signal word for hazard classification, and is supplied in bulk or research quantities. Molekula supplies Casein from bovine milk from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
