Chemical Structure

5,6-Dihydro-4H-pyran-2-carbonitrile CAS 31518-13-5 chemical structure

Description

The molecular framework of 5,6-Dihydro-4H-pyran-2-carbonitrile (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).

5,6-Dihydro-4H-pyran-2-carbonitrile (CAS 31518-13-5) is a high-purity analytical reference standard with the molecular formula C6H7NO and a molecular weight of 109.13 g/mol.

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), 5,6-Dihydro-4H-pyran-2-carbonitrile 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.
