About Tris buffer, 99%

Tris buffer (CAS 77-86-1) is a biological buffer offered by Vaqora Chemicals with a typical assay of 99%. Its molecular formula is C4H11NO3 and its molecular weight is 121.14 g/mol. Systematically, it is named 2-amino-2-(hydroxymethyl)propane-1,3-diol. Common synonyms include 2-Amino-2-(hydroxymethyl)-1,3-propanediol and THAM.

The material typically appears as a white crystalline powder. Reported physical data include a melting point of 165-170 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span buffer preparation, cell culture, electrophoresis and chromatography and molecular biology workflows. Our customers for this product work in academic and industrial research and diagnostics and biotechnology.

Vaqora Chemicals supplies Tris buffer in 100 g, 500 g, 1 kg and 5 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
