Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.24 g/mol gives 5-(Benzyloxy)salicylaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-(Benzyloxy)salicylaldehyde (CAS 56979-56-7), molecular formula C14H12O3 and molecular weight 228.24 g/mol, is a CATO reference standard with documented purity and traceability.
5-(Benzyloxy)salicylaldehyde (C14H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
