Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cypermethrin (1R,2S,1�R)-Isomer.
CATO supplies Cypermethrin (1R,2S,1�R)-Isomer (CAS 66841-24-5), a certified reference material (molecular formula C22H19Cl2NO3, MW 416.30 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Cypermethrin (1R,2S,1�R)-Isomer is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 416.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Cypermethrin (1R,2S,1�R)-Isomer 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.
