CAS:557-30-2 GLYOXIME 98+%

The substance corresponding to CAS No. 557-30-2 is GLYOXIME, also known as ETHANEDIAL DIOXIME, Pik-off, etc. Its molecular formula is C₂H₄N₂O₂, and its molecular weight is 88.0654.

GLYOXIME is a white to off-white solid. It has a density of 1.293g/cm³, a melting point ranging from 178 to 180°C, a boiling point of 310.229°C at 760 mmHg, a flash point of 188.015°C, a vapor pressure of 0 mmHg at 25°C, and a refractive index of 1.487. It is soluble in water and turns alkaline after dissolution.

Uses:

Agricultural field: GLYOXIME serves as an ethylene promoter and a fruit abscission agent for citrus. When a solution with a concentration of 200-400 mg/L is applied to citrus trees 5-7 days before harvesting, it can cause the fruits to be selectively shed, making them easier to pick, while being harmless to immature fruits and leaves.

Organic synthesis field: It can be utilized as a raw material for the synthesis of other organic substances and is an important organic synthesis intermediate.

Method of Preparation:
Generally Glyoxime is prepared by reacting malonic dianhydride and hydrazine to produce it. The reaction equation is as follows:
C2H4O2 + H2NNH2 → C2H4O2N2 + H2O
