Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Ethoxyphenyl)-3-oxopropanenitrile.
3-(2-Ethoxyphenyl)-3-oxopropanenitrile (CAS 89-44-1) is a high-purity analytical reference standard with the molecular formula C11H11NO2 and a molecular weight of 189.21 g/mol.
Structurally, 3-(2-Ethoxyphenyl)-3-oxopropanenitrile (C11H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 189.21 g/mol, it falls into the medium-molecular-weight range. 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-(2-Ethoxyphenyl)-3-oxopropanenitrile 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.
