Abstract: This study presents carbosulfan determination by a novel rapid, simple, sensitive and an extractive method, which is based on alkaline hydrolysis of carbosulfan into phenol followed by coupling with diazotized p- amino acetophenone in alkaline medium. Red brown dye (lmax 465 nm) can be extractable in 2-methyl butanol, which makes reaction more sensitive with same lmax. Beer’s law is obeyed between 0.8-5.6 ppm and 0.1-0.6 ppm in aqueous and extractive system respectively. Molar absorptivity and Sandell’s sensitivity were found to be 4.46x 10⁴ l mol⁻¹ cm⁻¹ and 0.0085 μg cm⁻² respectively. Method has been satisfactorily applied for carbosulfan determination in various environmental samples.
