Chemical Structure
Description
Structurally, Cypermethrin (1S,2R,1�R)-Isomer (C22H19Cl2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 416.30 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Cypermethrin (1S,2R,1�R)-Isomer (CAS 83860-32-6) is a high-purity analytical reference standard with the molecular formula C22H19Cl2NO3 and a molecular weight of 416.30 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
