Chemical Structure
Description
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.
2-methoxy-5-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (CAS 866546-13-6), molecular formula C14H19BO4 and molecular weight 262.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-methoxy-5-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (C14H19BO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
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.
