Description
(2R,3S,4S,5S)-5-Hydroxy-2,3,4-tris(phenylmethoxy)-5-[(phenylmethoxy)methyl]-cyclohexanone is a protected polyhydroxylated cyclohexanone derivative supplied at min. 95 % purity. It carries CAS number 115250-38-9, empirical formula C₃₅H₃₆O₆ and a molar mass of 552,66 g/mol. is intended for synthetic organic and carbohydrate-related research where a stereochemically defined, benzyl-protected intermediate is required. Multiple phenylmethoxy protecting groups and a free hydroxy function allow selective further transformation in multi-step sequences. This specialised building block from manufacturer Carl ROTH supports work in natural-product synthesis, chiral scaffold preparation and method development. Its well-documented molecular formula and stereochemical descriptors help ensure consistent experimental planning in advanced laboratory synthesis.
This article is part of Biological buffers (Tris, HEPES, MOPS), in Buffers & pH solutions.

Questions about (2R,3S,4S,5S)-5-Hydroxy-2,3,4-tris(phenylmethoxy)-5-[(phenylmethoxy)methyl]-c...
What is this article?
(2R,3S,4S,5S)-5-Hydroxy-2,3,4-tris(phenylmethoxy)-5-[(phenylmethoxy)methyl]-c... 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.
