Description

4-(Diethoxymethyl)benzaldehyde 81172-89-6 T1401 Terephthalaldehyde Mono(diethyl Acetal) (CAS 81172-89-6), molecular formula C12H22O3 and molecular weight 214.30 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H22O3, 4-(Diethoxymethyl)benzaldehyde 81172-89-6 T1401 Terephthalaldehyde Mono(diethyl Acetal) contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 214.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-(Diethoxymethyl)benzaldehyde 81172-89-6 T1401 Terephthalaldehyde Mono(diethyl Acetal) 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.
