Description

General description

O-(Tetrahydro-2H-pyran-2-yl)hydroxylamine (OTX) is an O-substituted hydroxylamine. The coupling of OTX with alkaline gel electrophoresis has been reported to improve the process of detecting single strand breaks (SSBs) in DNA.

Application

O-(Tetrahydro-2H-pyran-2-yl)hydroxylamine may be used in the synthesis of 2-(5-bromothiophene-2-sulfonamido)-N-(tetrahydro-2H-pyran-2-yloxy)acetamides.
It may be used in the synthesis of the following potential histone deacetylase (HDAC) inhibitors:

• 2-[1-(naphthalene-2-sulfonyl)-heterocyclyl]-pyrimidine-5-carboxylic acid (tetrahydropyran-2-yloxy)-amides
• (E)-3-(2-benzyl-1-oxoisoindolin-6-yl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide
• 3-(1-benzenesulfonyl-2,3-dihydro-1H-indol-5-yl)-N-hydroxy-acrylamide
