Category : Other Chemicals/Others
CAS NO : 103404-87-1 EC NO : 278-169-7 MF : C8H17N2NaO4S MW : 260.2863 Specification : White Powder Packing : 500g/bottle Product description : HEPES semi sodium is a commonly used zwitterionic buffer in biochemical laboratories, used to regulate the pH value of reaction systems. The following is an introduction to the relevant information about HEPES semi sodium: Composition and properties: HEPES half sodium, chemical full name N - (2-hydroxyethyl) piperazin-N '- (-2-ethanesulfonic acid) sodium salt, is a non-volatile zwitterionic chemical buffer. Its CAS number is 75277-39-3, and its appearance is white powder. HEPES semi sodium has a low toxic effect on cultured cells, so it is commonly used as a buffer for cell culture research. Usage and advantages: HEPES semi sodium serves as a buffer, which can control a constant pH range for a long time and has no toxic side effects on cells. Therefore, it is often used in virus preservation solutions or cell preservation solutions, cell cultures, and cosmetics. Due to its relatively stable chemical properties, HEPES semi sodium is also commonly used in the phosphorylation detection process of permeable fibroblasts. Usage and storage: After preparing a solution of powdered HEPES half sodium, it is necessary to label it in a timely manner to distinguish it from other solvents. The substance needs to be stored in a sealed container, in a cool and dry place, and away from oxidants. When impurities or mold appear in HEPES semi sodium powder or solution, it should be stopped and continued to be used. Avoid direct contact with human skin. If accidentally touching the skin, rinse immediately with plenty of water. If you still feel seek medical attention as soon as possible. Disposal: Unused HEPES semi sodium solution needs to undergo special treatment and meet relevant requirements before it can be discarded.
