Tris(hydroxymethyl)aminomethane (TRIS) CAS 77-86-1

• Packaging: 25 kg/drum. Custom packaging can be discussed based on order quantity and transportation requirements.

• Storage: Tris(hydroxymethyl)aminomethane (TRIS, CAS 77‑86‑1) is hygroscopic. Store in tightly‑sealed containers in a cool, dry, well‑ventilated area at 15‑25 °C away from heat, light, oxidants and acids, and reseal promptly after opening to avoid moisture caking.

Storage & Handling Notes

For solid Tris(hydroxymethyl)aminomethane (TRIS, CAS 77‑86‑1), prolonged exposure to high humidity or moisture may cause the material to absorb water and cake. Store in tightly sealed containers within a cool, dry and well‑ventilated environment, and avoid contact with acids and oxidizing agents.

Applications of Tris(hydroxymethyl)aminomethane (TRIS)

Tris(hydroxymethyl)aminomethane (TRIS, CAS 77-86-1) is a high-purity organic amine widely used as a biological buffer building block in biochemical reagent and biopharmaceutical formulations. Its molecular structure makes it particularly suitable for physiological-range buffer solutions, in-vitro diagnostic systems, and selected high-purity chemical synthesis processes.

Biological Buffers & Laboratory Reagents

TRIS is commonly used in the production of physiological pH buffer solutions for biological laboratory testing. Its amine-alcohol structure can support stable buffering capacity, low metal-ion interference, and formulation compatibility, making it suitable for life-science laboratory applications.

Typical application areas include:

• Biological experiment buffer systems

• Protein and nucleic acid purification reagents

• Biochemical analysis kits

• Cell culture medium additives

• Molecular biology test reagents

Diagnostic Kits & Biopharmaceutical Raw Materials

TRIS can be used in formulation systems designed for in-vitro diagnostic kits, biopharmaceutical intermediates, and biological reagent products. TRIS-based buffer formulations may provide a useful balance of biocompatibility and solution performance, including resistance to pH drift, good water solubility, and low cytotoxicity.

It is particularly suitable for formulations where stable pH buffering, high water-solubility, and low biotoxicity are required.

Cosmetic Raw Materials & Chemical Synthesis

TRIS is also used as a pH-adjusting component in cosmetic formulations and organic chemical synthesis. These systems are applied in personal-care products and fine-chemical production requiring mild pH adjustment and stable formulation performance.

Typical applications include:

• Cosmetic pH regulators

• Water-based personal-care formulations

• Organic synthesis intermediates

• Fine-chemical raw materials

In-vitro Diagnostics & Biopharma Formulations

TRIS-based buffer systems can be used in in-vitro diagnostic (IVD) and biopharmaceutical applications, particularly where pH stability and biological safety are important performance considerations.

The final performance of TRIS in any buffer or formulation system depends on the complete formulation, raw-material purity, processing conditions, storage environment, and intended end use. Customers should evaluate product suitability according to their specific formulation and application requirements.
