Chemical Structure
Description
The occurrence of 3-(tert-Butyl)-2-hydroxy-5-(4-pyridyl)benzaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(tert-Butyl)-2-hydroxy-5-(4-pyridyl)benzaldehyde (CAS 342037-22-3), molecular formula C16H17NO2 and molecular weight 255.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(tert-Butyl)-2-hydroxy-5-(4-pyridyl)benzaldehyde (C16H17NO2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
