Determination of genotoxic alkyl methane sulfonates and alkyl paratoluene sulfonates in lamivudine using hyphenated techniques

Two highly sensitive methods for the determination of genotoxic alkyl methane sulfonates (AMSs) and alkyl paratoluene sulfonates (APTSs) in lamivudine using hyphenated techniques have been presented. AMSs were determined by GC-MS method using GSBP-INOWAX (30 m×0.25 mm×0.25 μm) column. Temperature program was set by maintaining at 100 °C initially for 3 min, then rised to 220 °C at the rate of 1...

Synthesis of 14C-labeled alkyl polyoxyethylene detergents.

Procedures for the synthesis and purification of two 14C-labeled alkyl polyoxyethylene detergent preparations are described. One of the preparations consisted mainly of [14C]dodecyloctaoxyethylene ether, the other consisted mainly of [14C] octylhexaoxyethylene ether, with critical micellar concentrations of approximately 50 microM and 10 mM, respectively. Condensation of alkyl bromides with fra...

Towards Highly Activating Leaving Groups: Studies on the Preparation of Some Halogenated Alkyl Sulfonates

The trichloromethylsulfonyl-, dichloromethylsulfonyl-, chlorosulfonyl-, and fluorosulfonyl esters of a neopentyl-type alcohol have been prepared via sulfonylation or sulfinylation followed by oxidation. The preparative usefulness and potential of the transformations are discussed.
