Chemical Structure
Description
CATO manufactures 1R,3S,aR-Deltamethrin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1R,3S,aR-Deltamethrin (CAS 64363-97-9), molecular formula C22H19Br2NO3 and molecular weight 505.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1R,3S,aR-Deltamethrin (C22H19Br2NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
