2. Bis-tris propane - Wikipedia

   en.wikipedia.org/wiki/Bis-tris_propane

   Bis-tris propane, or 1,3-bis(tris(hydroxymethyl)methylamino)propane, also known as BTP, is a chemical substance that is used in buffer solutions. It is a white to off-white crystalline powder that is soluble in water. It has a wide buffering range, from 6 to 9.5 due to its two pK a values which are close in value.

3. MOPS - Wikipedia

   en.wikipedia.org/wiki/MOPS

   MOPS (3-(N-morpholino)propanesulfonic acid) is a buffer introduced in the 1960s, one of the twenty Good's buffers. It is a structural analog to MES, [1] and like MES, its structure contains a morpholine ring. HEPES is a similar pH buffering compound that contains a piperazine ring.

4. 2-Hydroxy-3-morpholinopropanesulfonic acid - Wikipedia

   en.wikipedia.org/wiki/2-Hydroxy-3-morpholinopro...

   MOPSO has been used as a buffer component for: [4] Copper analysis via: Flow injection micellar technique of the catalytic reaction of 3-methyl-2-benzothiazolinone hydrazone and N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline; Electrospray ionization quadrupole time-of-flight mass spectroscopy to measure MOPSO-copper chelated complexes

5. Good's buffers - Wikipedia

   en.wikipedia.org/wiki/Good's_buffers

   Good's buffers (also Good buffers) are twenty buffering agents for biochemical and biological research selected and described by Norman Good and colleagues during 1966–1980. [ 1 ] [ 2 ] [ 3 ] Most of the buffers were new zwitterionic compounds prepared and tested by Good and coworkers for the first time, though some ( MES , ADA , BES , Bicine ...

6. MES (buffer) - Wikipedia

   en.wikipedia.org/wiki/MES_(buffer)

   MES is used as a buffering agent in biology and biochemistry. It has pK a value of 6.15 at 20 °C. The pH (and pK a at ionic strength I≠0) of the buffer solution changes with concentration and temperature, and this effect may be predicted using online calculators. [2] MES is highly soluble in water. The melting point is approx. 300 °C.

7. Buffer solution - Wikipedia

   en.wikipedia.org/wiki/Buffer_solution

   The majority of biological samples that are used in research are kept in a buffer solution, often phosphate buffered saline (PBS) at pH 7.4. In industry, buffering agents are used in fermentation processes and in setting the correct conditions for dyes used in colouring fabrics. They are also used in chemical analysis [5] and calibration of pH ...

8. CAPS (buffer) - Wikipedia

   en.wikipedia.org/wiki/CAPS_(buffer)

   CAPS is the common name for 3-(Cyclohexylamino)-1-propanesulfonic acid, a chemical used as buffering agent in biochemistry. The similar substance N-cyclohexyl-2-hydroxyl-3-aminopropanesulfonic acid (CAPSO) is also used as buffering agent in biochemistry. Its useful pH range is 9.7-11.1.

9. Bis-tris methane - Wikipedia

   en.wikipedia.org/wiki/Bis-tris_methane

   Bis-tris methane, also known as BIS-TRIS or BTM, is a buffering agent used in biochemistry. Bis-tris methane is an organic tertiary amine with labile protons having a pKa of 6.46 at 25 °C. It is an effective buffer between the pH 5.8 and 7.2. Bis-tris methane binds strongly to Cu and Pb ions as well as, weakly, to Mg, Ca, Mn, Co, Ni, Zn and Cd.
