Chemical Structure
Description
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.
3-Allyl-4-[(4-chlorobenzyl)oxy]-5-ethoxybenzaldehyde (CAS 428470-93-3) is a high-purity analytical reference standard with the molecular formula C19H19ClO3 and a molecular weight of 330.81 g/mol.
The molecular framework of 3-Allyl-4-[(4-chlorobenzyl)oxy]-5-ethoxybenzaldehyde (C19H19ClO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
