Chemical Structure

3-Ethoxysalicylaldehyde CAS 492-88-6 chemical structure

Description

As a certified reference material (CRM), 3-Ethoxysalicylaldehyde 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 3-Ethoxysalicylaldehyde (CAS 492-88-6), a certified reference material (molecular formula C9H10O3, MW 166.18 g/mol) for analytical method development and quality control.

3-Ethoxysalicylaldehyde (C9H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
