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 1-(2-(2-Chlorophenoxy)ethyl)-2-methyl-1H-indole-3-carbaldehyde.
CATO supplies 1-(2-(2-Chlorophenoxy)ethyl)-2-methyl-1H-indole-3-carbaldehyde (CAS 433241-35-1), a certified reference material (molecular formula C18H16ClNO2, MW 313.78 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-(2-Chlorophenoxy)ethyl)-2-methyl-1H-indole-3-carbaldehyde (C18H16ClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), 1-(2-(2-Chlorophenoxy)ethyl)-2-methyl-1H-indole-3-carbaldehyde 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.
