Calcium hydrogencarbonate (Ca(CO₃H)₂) is a water-soluble calcium salt used primarily in water treatment, pH buffering, and as a mild antacid. In food manufacturing it also serves as an additive, acting as an anti-caking agent, stabilizer and surface colorant. It occurs naturally in hard water and is employed in industrial processes to adjust alkalinity and stabilize solutions. CAS 3983-19-5, molecular weight 162.11 g/mol, stored at ambient conditions. Signal word: Warning. Molekula supplies calcium hydrogencarbonate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
