BIS-TRIS Propane is Good′s buffer. It acts as ligand and forms series of dinuclear hydroxo complexes with Lanthanides(III) in the pH range 7-9. It is useful for diagnostic assay manufacturing industry.

White powder

BIS-Tris Propane is a buffer that is useful in the pH 6.3 - 9.5 range. This wide buffering range is due to its two pKa values, 6.8 (pKa1) and 9.0 (pKa2), being so close. Because of the wide buffering range, particularly down to pH 6 - 7, this buffer has been used to enhance the stability or activity of restriction enzymes, compared to Tris buffer (which is a poor buffer below pH 7.5 and has a comparatively large change in pKa with temperature).

BIS-TRIS Propane may be used in the following studies:
As buffer to investigate the influence of anions with varying nucleophilic properties on the autoxidation of oxymyoglobin (MbO2).
Purification of glucose-binding protein from membranes of Sulfolobus solfataricus.
As buffer during GeO2 mineralisation.

ChEBI: Bis-tris propane is a water-soluble buffer substance used for the preparation of the biochemical and biological buffer solutions; pKa = 6.8 at 20 ℃. It has a role as a buffer. It is functionally related to a member of tris.

This trihydroxyamine analog, also known as bis-tris propane, presents as a white to almost white crystalline powder. Store in a cool and dark place. 1,3-Bis[tris(hydroxymethyl)methylamino]propane is known to be incompatible with oxidizing agents and should not be handled in their vicinity.
