Chemical Structure
Description
As a certified reference material (CRM), 2-(3-chlorophenyl)acetaldehyde 2-(3-chlorophenyl)ethanal 41904-40-9 A825690 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.
CATO supplies 2-(3-chlorophenyl)acetaldehyde 2-(3-chlorophenyl)ethanal 41904-40-9 A825690 (CAS 41904-40-9), a certified reference material (molecular formula C8H7ClO, MW 154.59 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-chlorophenyl)acetaldehyde 2-(3-chlorophenyl)ethanal 41904-40-9 A825690 (C8H7ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
