8-Methoxy-2-oxo-2H-chromene-3-carbonitrile CAS 13229-91-9

Description

The occurrence of 8-Methoxy-2-oxo-2H-chromene-3-carbonitrile is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

8-Methoxy-2-oxo-2H-chromene-3-carbonitrile (CAS 13229-91-9), molecular formula C11H7NO3 and molecular weight 201.18 g/mol, is a CATO reference standard with documented purity and traceability.

8-Methoxy-2-oxo-2H-chromene-3-carbonitrile (C11H7NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 8-Methoxy-2-oxo-2H-chromene-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
