Description
MOPS, PUFFERAN®, is a molecular biological buffer reagent supplied at a minimum purity of 99,5 %. The substance is identified by CAS number 1132-61-2 and empirical formula C₇H₁₅NO₄S, with a molar mass of 209,27 g/mol. Documented physical properties include a flash point of 116 °C and a boiling point of 354,6 °C; the European inventory reference is EG nr. 214-478-5. The material is available from manufacturer Carl ROTH within the PUFFERAN® buffer range. Its clearly stated assay and physicochemical data support preparation of aqueous buffer systems under controlled laboratory conditions. offers a practical quantity for routine molecular biology reagent handling while retaining the specified minimum content of 99,5 %. Laboratories working with molecular biological buffers benefit from the combination of high stated purity, full CAS and EG identification, and the convenient pack size for everyday buffer formulation tasks.
This article belongs on Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about MOPS, PUFFERAN®, min. 99,5 %, 250 g, plastic
What is this article?
MOPS, PUFFERAN®, min. 99,5 %, 250 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 Produits chimiques de laboratoire et industriels.
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.
