Reference of 87851-77-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 87851-77-2, name is O-(3-Chloroallyl)hydroxylamine belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

The cyclohexanone derivatization method is described immediately below. Weigh about 2.00 g of sample in a vial containing 2.20 g of cyclohexanone; Add 50percent sodium hydroxide if necessary to bring pH to above 9. Stir the mixture in the capped vial at 50° C. for 2 hours. After cooling, add 8.0 g of dichloromethane and shake for one minute. Settle the mixture for 5 minutes. Take the organic phase for gas chromatographic (GC) analysis. CPHA purity and impurity profile are directly based on GC area. Hydroxylamine content is calculated based on the integration area of cyclohexanone oxime (cyclohexanoxime) peak and O-(chloro-2-propenyl)cyclohexanoxime peak.

The synthetic route of O-(3-Chloroallyl)hydroxylamine has been constantly updated, and we look forward to future research findings.
