Chemical Structure
Description
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.
2-[(3E)-Oxolan-3-ylidene]acetonitrile (CAS 1629072-86-1) is a high-purity analytical reference standard with the molecular formula C6H7NO and a molecular weight of 109.13 g/mol.
The molecular framework of 2-[(3E)-Oxolan-3-ylidene]acetonitrile (C6H7NO) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-[(3E)-Oxolan-3-ylidene]acetonitrile 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.
