The IUPAC name of DMT-Cl is 2-chloro-4-methoxy-1-[(4-methoxyphenyl)-phenylmethyl]benzene . With the CAS registry number 40615-36-9, it is also named as 1,1'-(Chlorophenylmethylene)bis(4-methoxybenzene) ; Benzene, 1,1'-(chlorophenylmethylene)bis(4-methoxy- ; Methane, chlorobis(p-methoxyphenyl)phenyl- ; 4,4'-Dimethoxytriphenylmethyl chloride .

The DMT-Cl is pink powder which is sensitive to moisture. It should be stored at 0°C. This product is used as 5'-hydroxyl protecting group of nucleoside. It is irritating to eyes, respiratory system and skin. People should not breathe dust and avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If you want to contact this product, you must wear suitable protective clothing. 

The DMT-Cl also can be used in many organic synthesis. For example: 1. It reacts with 4-N-nicotinoyl-2'-deoxycytidine to get 5'-O-(4,4'-dimethoxytrityl)-4-N-nicotinoyl-2'-deoxycytidine ; 2. It can react with xylouridine-3'-(O-methyl)-(O-aminophenazine-6-hexyl)-phosphate to obtain phosphoric acid 2-[bis-(4-methoxy-phenyl)-phenyl-methoxymethyl]-5-(2,4-dioxo-3,4-dihydro-2H-pyrimidin-1-yloxy)-4-hydroxy-tetrahydro-furan-3-yl ester methyl ester 6-(phenazin-2-yl-phenoxyacetyl-amino .
