Carbon Diselenide (Methanediselone) Se=C=Se CSe2 molecular mass: 169.93 g/mol molecular formula: CSe2 (CSe2) boiling point: 125-126 °C (lit.) stability: decomposes slowly about 1% per month at -30 °C solubility:good in organic solvents, insoluble in water other: light sensitive, strong unpleasant odor main use: synthesis of organic conductors and superconductors such as selenium analogs of tetrathiafulvalene (TTF) derivatives - tetraselenafulvalene appearance: yellow-orange liquide normal density: 2.66 g/ml (lit.) name(s): carbon diselenide, carbon selenide, methanediselone, carbon(IV) selenide, 1,3-diselenapropadiene, 1,3-diselenaallene CAS No.: [506-80-9] Merck (12th Ed.): 1858 UQF No.: QS.500091 Aprox. prices: 1) carbon diselenide +98% (GC-MS) 1 g - 5984.00 EUR 5 g - 9415.00 EUR 10 g - 12,887.00 EUR 25 g - 19,710.00 EUR 100 g - 31,045.00 EUR 250 g - 40,155.00 EUR 500 g - 58,340.00 EUR 2) carbon diselenide +99% (GC-MS) prices are 15% higher than for 98% purity 3) carbon diselenide (+98 or +99%), ~5% solution in solvent prices are based on neat CSe2 prices and additional fee: 1 - 10 g of CSe2 - 257.00 EUR 11 - 50 g of CSe2 - 284.00 EUR 51 - 125 g of CSe2 - 372.00 EUR 126 - 500 g of CSe2 - 458.00 EUR solvents: diethyl ether, THF, NMP, benzene, cyclohexane, dioxane, dichloromethane, tetrachloroethylene, pentane available containers: orange glass bottles 30 ml, 100 ml, 250 ml, 500 ml, 1000 ml, 2500 ml with PTFE seal solutions are more stable than neat product Prices denominated in other currencies on request (USD, PLN, GBP, CHF, AUD, CAD, JPY) We offer also the product in the form of stabilized solution, where carbon diselenide composes an adduct with special solvents. Such solutions are more stable and may be used in this form or carbon diselenide can be recovered after evaporation of solvent. CSe2 Mirror Page Dwuselenek węgla (Polish) |
