Beschrijving
4.4'-Dimethoxytrityl chloride is een beschermgroepreagens voor synthese, aangeboden met een minimale zuiverheid van 98 %. Het heeft CAS-nummer 40615-36-9, empirische formule C₂₁H₁₉ClO₂, molaire massa 338.83 g/mol en EG-nummer 255-002-6. De dimethoxytrityl (DMT)-groep wordt routinematig ingevoerd om primaire hydroxylgroepen af te schermen, vooral in nucleoside- en oligonucleotidechemie, waar zuurlabiele bescherming en handige monitoring voordelig zijn. Dit materiaal voor synthese van fabrikant Carl ROTH is Met zijn gedefinieerde gehalte en klassieke tritylreactiviteit ondersteunt 4.4'-Dimethoxytrityl chloride de selectieve installatie van de DMT-groep onder standaard watervrije omstandigheden die in organische en nucleïnezuurgerelateerde workflows worden gebruikt.
Dit artikel maakt deel uit van Anorganische zouten, in Anorganische chemicaliën.

Questions about 4.4'-Dimethoxytrityl chloride, min. 98 %, voor synthese, 5 g, glas
What is this article?
4.4'-Dimethoxytrityl chloride, min. 98 %, voor synthese, 5 g, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Anorganische zouten, inside Anorganische chemicaliën, in Chemicaliën.
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?
The category is Anorganische chemicaliën. The sub-category is Anorganische zouten. The catalogue is Chemicaliën.
Shelves beside this one are Metalen, elementen & oxiden and Nanomaterialen & kwantumdots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
