The Leurocristine sulfate (1:1), with the CAS registry number 2068-78-2 and EINECS registry number 218-190-0, has the systemaic name of (2α,2'β,3α,4α,5β,19β)-22-oxovincaleukoblastine sulfate (1:1). And the molecular formula of this chemical is C₄₆H₅₆N₄O₁₀^.H₂SO₄. It is a kind of crystalline solid, and usually used as antineoplastic and monoamine oxidase inhibitor. What's more, it is sensitive to hydrolysis, oxidation and heat, and incompatible with strong oxidizing agents. In addition, it should be stored at 2-8°C.

The physical properties of Leurocristine sulfate (1:1) are as following: (1)ACD/LogP: 2.82; (2)# of Rule of 5 Violations: 2 ; (3)#H bond acceptors: 14; (4)#H bond donors: 3; (5)#Freely Rotating Bonds: 12; (6)Polar Surface Area: 138.31 Å².

You should be cautious while dealing with this chemical. It irritates eyes, respiratory system and skin, and it is also toxic by inhalation, in contact with skin and if swallowed. What's more, it may cause harm to the unborn child. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; Do not breathe dust and then try to avoid contacting with skin and eyes; Avoid exposure - obtain special instruction before use; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
