Description
AMPSO sodium salt is a zwitterionic buffer salt offered as PUFFERAN® with a minimum purity of 98 %. It is identified by CAS number 102029-60-7, the empirical formula C₇H₁₆NO₅SNa and a molar mass of 249,3 g/mol. The sodium salt form dissolves readily for preparation of aqueous buffer systems used in biochemical and molecular-biology applications where stable pH control in the alkaline range is required. This variant is PUFFERAN® quality supports consistent ionic strength and buffering capacity across batches. From manufacturer Carl ROTH, AMPSO sodium salt belongs to the buffer-salt portfolio for performance materials and laboratory reagents. Prepare solutions according to your protocol, verify pH after dilution and store the solid under dry conditions as recommended in the product documentation.
This article belongs on Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about AMPSO sodium salt, PUFFERAN®, min. 98 %, 25 g, plastic
What is this article?
AMPSO sodium salt, PUFFERAN®, min. 98 %, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biological buffers (Tris, HEPES, MOPS), inside Buffers & pH solutions, in Lab chemicals.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
