Chemical Structure
Description
The occurrence of 4-Cyclopropoxy-3-ethylbenzaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Cyclopropoxy-3-ethylbenzaldehyde (CAS 1243344-41-3), molecular formula C12H14O2 and molecular weight 190.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Cyclopropoxy-3-ethylbenzaldehyde (C12H14O2) 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 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.
As a certified reference material (CRM), 4-Cyclopropoxy-3-ethylbenzaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
