Chemical Structure
Description
The occurrence of 3,5-Diphenylsalicylaldehyde; 2-Hydroxy-3,5-diphenylbenzaldehyde is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Diphenylsalicylaldehyde; 2-Hydroxy-3,5-diphenylbenzaldehyde (CAS 402576-65-2), a certified reference material (molecular formula C19H14O2, MW 274.31 g/mol) for analytical method development and quality control.
The molecular framework of 3,5-Diphenylsalicylaldehyde; 2-Hydroxy-3,5-diphenylbenzaldehyde (C19H14O2) is characterized by a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 3,5-Diphenylsalicylaldehyde; 2-Hydroxy-3,5-diphenylbenzaldehyde 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.
