Tris-(2-carboxy-ethyl)-sulfonium chloride, also known as TES, is a zwitterionic buffer commonly used in biological research and applications. It is a salt formed from the reaction of tris-(2-carboxy-ethyl)-sulfonium with hydrochloric acid. TES has a pKa of approximately 7.2, making it suitable for maintaining a stable pH in biological buffers, particularly in the neutral to slightly alkaline range. It is often used in place of other buffers like Tris or HEPES due to its resistance to hydrolysis and its ability to maintain a stable pH even in the presence of divalent cations. TES is also known for its low UV absorbance, which makes it a preferred choice in applications where minimizing interference with spectroscopic measurements is crucial, such as in enzyme assays or chromatography.

39669-77-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39669-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,6,6 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 39669-77:
(7*3)+(6*9)+(5*6)+(4*6)+(3*9)+(2*7)+(1*7)=177
177 % 10 = 7
So 39669-77-7 is a valid CAS Registry Number.
