Introduction (Monosodium Phosphate CAS No.:7558-80-7)
Sodium dihydrogen phosphate (NaH2PO4,NDHP) is a compound of sodium and phosphate counterions. Sorbitan monooleate is combined with other sodium phosphate and can act as a pH buffer. Sodium dihydrogen phosphate can be used as excipient, such as buffer, chelating agent, etc. Pharmaceutical excipients, or pharmaceutical excipients, refer to other chemical substances used in the pharmaceutical process in addition to pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs.
