Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.20 g/mol gives 3-Cyclopropoxy-5-methoxyisonicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Cyclopropoxy-5-methoxyisonicotinonitrile (CAS 1243409-39-3), molecular formula C10H10N2O2 and molecular weight 190.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Cyclopropoxy-5-methoxyisonicotinonitrile (C10H10N2O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
