Description
4,4'-Dimethoxytrityl chloride is a protecting-group reagent for synthesis, offered at a minimum purity of 98 %. It has CAS number 40615-36-9, empirical formula C₂₁H₁₉ClO₂, molar mass 338,83 g/mol and EG number 255-002-6. The dimethoxytrityl (DMT) moiety is routinely introduced to shield primary hydroxyl groups, especially in nucleoside and oligonucleotide chemistry, where acid-labile protection and convenient monitoring are advantageous. This material for synthesis from manufacturer Carl ROTH is With its defined assay and classic trityl reactivity, 4,4'-dimethoxytrityl chloride supports selective installation of the DMT group under standard anhydrous conditions used in organic and nucleic-acid-related workflows.

Questions about 4,4'-Dimethoxytrityl chloride, min. 98 %, for synthesis, 5 g, glass
What is this article?
4,4'-Dimethoxytrityl chloride, min. 98 %, for synthesis, 5 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
Which category should I open next?
