Chemical Properties

Clear colorless to yellow liquid

Purification Methods

The ester reacts slowly with H2O and aqueous alkali. If its IR has no OH bands (~3000 cm-1) then purify it by redistillation. If OH bands are present, then dilute with dry Et2O and shake (carefully) with aqueous NaHCO3 until effervescence ceases, then wash with H2O and dry (MgSO4), filter, evaporate and distil the residue under a slight vacuum then at atmospheric pressure in a N2 atmosphere. IT IS A POWERFUL ALKYLATING AGENT, AND THE FUMES ARE VERY TOXIC — PERFORM ALL OPERATIONS IN AN EFFICIENT FUME CUPBOARD.
