Calcium Hydrogen Phosphate forms and their CAS numbers, structured for ERP or supplier documentation clarity:
Types and CAS Numbers
| Form | Chemical Name | CAS No | Notes |
|---|---|---|---|
| Anhydrous | Calcium hydrogen phosphate (dibasic, anhydrous) | 7757-93-9 | Most common form; widely used in pharmaceuticals as excipient and in food as additive (E341(ii)) |
| Dihydrate (Brushite) | Calcium hydrogen phosphate dihydrate | 7789-77-7 | Less stable; occurs in dental/bone mineralization studies |
| Monohydrate | Calcium hydrogen phosphate monohydrate | 10031-30-8 | Rare; specific pharmaceutical applications |
| Tricalcium phosphate | Ca₃(PO₄)₂ | 7758-87-4 | Technically a different phosphate salt; sometimes confused with dibasic form |
Key Takeaways
-
CAS 7757-93-9 (Anhydrous) → Most relevant for trade, compliance, and ERP documentation.
-
CAS 7789-77-7 (Dihydrate) → Brushite, more research-oriented.
-
CAS 10031-30-8 (Monohydrate) → Specialty use.
-
CAS 7758-87-4 (Tricalcium phosphate) → Different compound, but often listed alongside dibasic forms.
