Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-(Ethyl(2-hydroxyethyl)amino)-2-methylbenzaldehyde (CAS 21850-52-2), a certified reference material (molecular formula C20H11Cl2I2NO3, MW 638.02 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Ethyl(2-hydroxyethyl)amino)-2-methylbenzaldehyde (C20H11Cl2I2NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 4-(Ethyl(2-hydroxyethyl)amino)-2-methylbenzaldehyde 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.
