Chemical Structure
Description
The occurrence of 3-(4-Ethyl-2-methylphenyl)propanal is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(4-Ethyl-2-methylphenyl)propanal (CAS 180274-34-4), molecular formula C12H16O and molecular weight 176.25 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Ethyl-2-methylphenyl)propanal (C12H16O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3-(4-Ethyl-2-methylphenyl)propanal 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.
