TRIS (Tris(hydroxymethyl)aminomethane) is a widely used buffering agent and pH stabilizer in biochemical, pharmaceutical, and molecular biology applications, including cell culture media, protein purification, and DNA/RNA research. It is also employed in electrophoresis and as a standard in biochemical assays due to its buffering capacity near physiological pH. This high-purity TRIS (≥ 99.9%) has a CAS number of 77-86-1, molecular formula NH2C(CH2OH)3, and a molecular weight of 121.14. It is stored at ambient conditions, with a signal word of Warning for safety classification. Molekula supplies TRIS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
