Chemical Structure
Description
CATO supplies 5-Cyclopropoxy-3-ethylpicolinic acid (CAS 1243393-48-7), a certified reference material (molecular formula C11H13NO3, MW 207.23 g/mol) for analytical method development and quality control.
The molecular framework of 5-Cyclopropoxy-3-ethylpicolinic acid (C11H13NO3) is characterized by an amino-acid-derived structure, 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.
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), 5-Cyclopropoxy-3-ethylpicolinic acid 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.
