 | Hazard Information | Back Directory |  | [Chemical Properties] 
 Clear colorless liquid
 |  | [Uses] 
 O-benzylhydroxylamine used in the synthesis of alfa- hydroxybenzylamines from alfa-hydroxyketones. It is also involved in the preparation of  hydroxylamines and hydroxyamates.
 |  | [Application] 
 A reagent for the preparation of N-hydroxyamides (including N-hydroxypeptides and N-hydroxyβ-lactams) and hydroxamic acids; a derivatizing agent for ketones, aldehydes and carbohydrates.
 |  | [Preparation] 
 The free base O-benzylhydroxylamine, a liquid of bp 115-119 °C/30 mmHg, is easily prepared from the commercially available hydrochloride salt. For many reactions, however, it is preferable to generate the free base in situ from the salt.
 |  | [storage] 
 Store in a cool dry place to preclude contact with moisture and oxygen; may be harmful by inhalation, ingestion, or skin absorption; avoid contact with the eyes.
