Product Name:4,4'-Dimethoxytrityl chloride
English Name:4,4'-Dimethoxytrityl chloride
CAS No.:40615-36-9
Aliases:DMT-Cl, 4,4'-Dimethoxytrityl chloride, Bis(4-methoxyphenyl)(phenyl)methyl chloride
Molecular Formula:C21H19ClO2
Physical Properties:White to off-white crystalline powder, melting point approximately 114–117°C. Soluble in organic solvents such as dichloromethane, acetonitrile, and pyridine. Slowly decomposes upon contact with water or moisture, releasing hydrogen chloride. Stable under dry conditions; store sealed and protected from light.
Uses:Primarily used as a 5'-hydroxyl protecting reagent in oligonucleotide synthesis, introducing the dimethoxytrityl (DMT) protecting group by reacting with the 5'-hydroxyl group of nucleosides; widely applied in solid-phase DNA/RNA synthesis. Also employed as a selective protecting reagent for alcohols and amines in organic synthesis.
Technical Specifications:
Assay (HPLC) ≥98.0%
Melting point range: 114–117°C
Loss on drying ≤0.5%
Free chlorine ≤0.1%
Clarity of solution: clear when 0.5 g dissolved in 10 mL dichloromethane
