Principle: Formic acid gradually dissolves calcium salts such as hydroxyapatite through a mildly acidic environment, and its chemical reaction formula is: Ca₁₀(PO₄)₆(OH)₂ + 20HCOOH → 10Ca(HCOO)₂ + 6H₃PO₄ + 2H₂O . Compared to strong acids such as nitric acid, formic acid decalcifies slower but causes less damage to tissue structure, making it more suitable for samples that require preservation of cell morphology and antigenic activity.
Main components: Formic acid
