About Tris buffer, GR 99%+

Tris buffer is a biological buffer (AR grade) carrying the CAS registry number 77-86-1 with a typical assay of ≥99%. With the molecular formula C4H11NO3, it has a molar mass of 121.14 g/mol. Its systematic (IUPAC) name is 2-amino-2-(hydroxymethyl)propane-1,3-diol. It is also known as 2-Amino-2-(hydroxymethyl)-1,3-propanediol or THAM.

In its supplied form it is a white powder or crystals or crystalline powder. Key physical data: a melting point of 167-172 °C. Store in a tightly closed container in a cool, dry and well-ventilated place. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

Typical applications include buffer preparation, cell culture and electrophoresis and chromatography. It is used across academic and industrial research and diagnostics and biotechnology.

We offer Tris buffer in 100 g, 500 g, 1 kg and 5 kg packs with a batch-specific COA, and ship to customers worldwide.
