Chemical Structure

Pyriproxyfen CAS 95737-68-1 chemical structure

Description

The molecular framework of Pyriproxyfen (C20H19NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Pyriproxyfen (CAS 95737-68-1) is a high-purity analytical reference standard with the molecular formula C20H19NO3 and a molecular weight of 321.37 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Pyriproxyfen meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
