Applications of 77-86-1
| Industry | Application | Process |
|---|---|---|
| Biomedical Research | Buffer component for electrophoresis, DNA/RNA extraction, PCR, and related assays | Formulated into Tris-HCl buffer solutions (pH 7.0–9.0) to maintain stable pH in reaction systems |
| Pharmaceutical Industry | pH adjuster and stabilizer in drug formulations, including injectables, ophthalmic solutions, and protein-based therapeutics | Added to final sterile formulations to control pH within physiologically compatible ranges (e.g., 7.2–7.6) |
| Cosmetics | pH adjuster and skin-conditioning agent in conditioners, shampoos, and skincare products | Neutralized with acid (e.g., hydrochloric acid) prior to incorporation to ensure product pH of 4.5–6.5, supporting skin barrier function |
| Molecular Diagnostics Reagents | Core buffering component in nucleic acid detection kits | Serves as a foundational component in RT-PCR and isothermal amplification (e.g., LAMP) reaction buffers to ensure enzymatic activity and specificity |
| Cell Culture | Supplement for pH adjustment of basal media (e.g., MEM, DMEM) | Used in conjunction with CO₂ equilibrium systems to enhance pH buffering capacity, particularly under low-CO₂ or CO₂-free culture conditions |
