Dibasic Sodium Phosphate Anhydrous CPH8 PARENTEX PLUS 5KG is a high-purity inorganic phosphate salt (anhydrous Na₂HPO₄), developed from pharmacopeial-grade sodium phosphate systems (USP/Ph.Eur/BP), and further optimized into the CPH8 – PARENTEX PLUS grade to support formulation systems requiring precise pH control and high stability in industrial manufacturing.
From a chemical perspective, this is a mildly alkaline phosphate salt system capable of:
However, the true differentiation lies not in its chemical name, but in how the material is engineered for formulation performance. Compared to conventional sodium phosphate anhydrous (base grade), CPH8 PARENTEX PLUS is more tightly controlled in terms of:

Criteria | Sodium Phosphate Anhydrous (CPH8) | Sodium Phosphate Anhydrous (Base) | Calcium Phosphate Dihydrate |
| Solubility | Fully soluble in water | Fully soluble in water | Insoluble |
| Primary role | Buffer system + functional excipient for formulation control | Basic chemical buffer | Filler + structural excipient |
| pH control capability | Strong (complete buffer system, stable microenvironment) | Moderate (basic pH adjustment only) | Minimal |
| Compressibility | Moderate, stable in industrial blending | Moderate | Excellent (strong direct compression support) |
| Main applications | Solutions, effervescent tablets, pH-sensitive formulations | Basic formulations with low stability requirements | Solid tablets, direct compression, high hardness systems |
| Technological role | Engineered functional excipient – controls formulation behavior | Raw excipient – single function | Structural excipient provides mechanical framework |
