CAS 2386-60-9 Uses
1-Butanesulfonyl chloride has been used in the preparation of:（1）ethyl 2-(1-butanesulfonamido)pent-4-yn-l-oate
（2）1-butanesulfonamid-N,N′-1,2-ethanediylbis
（3）1-butanesulfonamide-N,N′-1,3-propanediylbis
Purification Methods
It has a pungent odour and is LACHRYMATORY. If IR shows OH bands, then dissolve in Et2O, wash with cold saturated aqueous NaHCO3 (care since CO2 will be generated) then H2O, dry it over solid Na2SO4, filter, evaporate and distil the residue twice. Characterise it by shaking a solution in Et2O or *C6H6 with aqueous NH3, collect the solid 1-butanesulfonamide with m 48o after recrystallisation from CHCl3, CCl4 or Et2O/pet ether.
