Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]benzaldehyde.
CATO supplies 4-[4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]benzaldehyde (CAS 2490666-01-6), a certified reference material (molecular formula C19H21BO4, MW 324.18 g/mol) for analytical method development and quality control.
Structurally, 4-[4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]benzaldehyde (C19H21BO4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 324.18 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 4-[4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]benzaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
