Chemical Structure
Description
As a certified reference material (CRM), 4-oxo-4H-chromene-7-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.
4-oxo-4H-chromene-7-carbonitrile (CAS 102297-64-3) is a high-purity analytical reference standard with the molecular formula C10H5NO2 and a molecular weight of 171.15 g/mol.
The molecular framework of 4-oxo-4H-chromene-7-carbonitrile (C10H5NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
