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.
(E)-3,5-di-tert-butyl-4-hydroxybenzaldehyde O-methyl oxime (CAS 14446-64-1) is a high-purity analytical reference standard with the molecular formula C16H25NO2 and a molecular weight of 263.38 g/mol.
The molecular framework of (E)-3,5-di-tert-butyl-4-hydroxybenzaldehyde O-methyl oxime (C16H25NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (E)-3,5-di-tert-butyl-4-hydroxybenzaldehyde O-methyl oxime 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.
