Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-ethoxy-5-iodo-4-propoxybenzaldehyde.
3-ethoxy-5-iodo-4-propoxybenzaldehyde (CAS 834907-89-0) is a high-purity analytical reference standard with the molecular formula C12H15IO3 and a molecular weight of 334.15 g/mol.
The molecular framework of 3-ethoxy-5-iodo-4-propoxybenzaldehyde (C12H15IO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 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.
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.
As a certified reference material (CRM), 3-ethoxy-5-iodo-4-propoxybenzaldehyde 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.
