Frequently Asked Questions
Where can I buy DCP Dihydrate (Dicalcium Phosphate Dihydrate) in Hyderabad?
Surravi Phharma supplies DCP Dihydrate (CaHPO₄·2H₂O) in IP, BP, EP, and USP grades in Hyderabad with ready stock. Used in wet granulation tablet manufacturing and calcium supplement formulations. Call +91 8008002576.
Is DCP Dihydrate better than DCP Anhydrous for wet granulation?
Yes. DCP Dihydrate has superior compressibility properties and is the preferred grade for wet granulation tablet manufacturing. Its water content (~21%) is locked in the crystal lattice and does not adversely affect moisture-sensitive APIs in properly dried granules. For direct compression, the anhydrous grade is preferred.
What is the assay specification for pharma grade DCP Dihydrate?
Pharma grade DCP Dihydrate (CaHPO₄·2H₂O) should assay 98.0–105.0% as CaHPO₄ on the dried basis. Water of crystallisation is approximately 21%. The IP/USP specifications also limit heavy metals (NMT 20 ppm), fluoride, arsenic, and microbiological contamination.
Can DCP Dihydrate be used in Calcium + Vitamin D3 tablet formulations?
Yes. DCP Dihydrate is frequently used as both the tablet filler and calcium source in Calcium + Vitamin D3 combination tablets. Each 1000 mg of DCP Dihydrate provides approximately 232 mg elemental calcium. The Vitamin D3 component (as cholecalciferol) is typically incorporated via a premix or oil dispersion.
Is DCP Dihydrate compatible with Vitamin D3 and other vitamins?
DCP Dihydrate is slightly alkaline (pH ~7.2 in suspension), which is generally compatible with Vitamin D3, Vitamin K2, and most B vitamins. However, it may slightly accelerate the oxidation of Vitamin C (ascorbic acid) in the same formulation. When formulating multivitamin tablets with DCP, include antioxidants such as Vitamin E or BHT.
