Uses
Different sources of media describe the Uses of 71119-23-8 differently. You can refer to the following data:
1. MES sodium salt is a buffering agent used in biological and biochemical research including plant cell culture.
2. MES sodium salt has been used:To achieve the required density and stretching of DNA fibers during melting of agarose plugs containing genomic DNATo equilibrate the Balch homogenizer chamber and to prevent sample hydrolysis before sample homogenization
3. MES Sodium is a biological buffer often referred to as a “Good′s” buffer. The pKa of MES is 5.96 which makes MES an ideal candidate for cell culture media and protein based buffer formulations to maintain a stable environment in solution. MES Sodium is considered to be non-toxic to culture cell lines, highly water soluble and provides high-solution clarity.MES Sodium is used in cell culture media, biopharmaceutical buffer formulations (both upstream and downstream) and diagnostic reagents. MES based buffers are used in purification bioprocesses of antibodies, peptides, proteins and blood components.
Definition
ChEBI: The organic sodium salt that is the sodium salt of 2-(N-morpholino)ethanesulfonic acid.
General Description
MES is one of the so-called "Good" buffers developed for biological applications. This product is BioPerformance certified (suitable for electrophoresis, tissue culture, and molecular biology applications. A buffer using MES free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pKa=±1). Alternatively, volumes of equimolar solutions of MES free acid and MES sodium can be mixed to attain the desired pH. Standard mixing tables using stock solutions to prepare a buffer of a given pH have been published.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 71119-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,1 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71119-23:
(7*7)+(6*1)+(5*1)+(4*1)+(3*9)+(2*2)+(1*3)=98
98 % 10 = 8
So 71119-23-8 is a valid CAS Registry Number.

Preparation of substituted alkanesulfonates from 2-hydroxyalkanesulfonates
-
Page/Page column 4; 6, (2008/06/13)
The present invention relates to a process for the preparation of substituted alkanesulfonates by the reaction of an aqueous metal substituted 2-hydroxyethanesulfonate with a nucleophile. 2-Alkylaminoalkanesulfonate is formed when the nucleophile is an amine. The invention also relates to the optimization of reaction conditions to produce an optimum yield.
