Detailed introduction
1. Product Description
Sodium dihydrogen phosphate, also known as acidic sodium phosphate, has a relative average molecular mass of 119.98. It is divided into anhydrous and dihydrate. The dihydrate is colorless to white crystalline or crystalline powder, and the anhydrous is white powder or granule. Soluble in water, almost insoluble in ethanol, the aqueous solution is acidic. After the loss of water of crystallization at 100 ℃, heating is continued to generate acidic sodium pyrophosphate, and the pH of 0.1mol/L aqueous solution at 25 ℃ is 4.5. Relative density 1.915. Melting point 60 ℃. Commodities also have a molecule of crystal water.

3. Product Application
pH regulatorThe phosphate buffer system is one of the most widely used buffer systems in biochemical research and has the following advantages:
1) easy to prepare into various concentrations of buffer;
2) The applicable pH range is wide;
3)pH is less affected by temperature;
4) After buffer dilutionThe change of pH is small, such as the change of pH after ten times dilution is less than 0.1.
4. Characteristic R & D service
1. National Pharmacopoeia Detection Operation Decomposition Guidance
2. Customized specialty preparation services
