Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 236.26 g/mol gives Ethyl 6-methoxychromane-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 6-methoxychromane-3-carboxylate (CAS 885271-71-6), molecular formula C13H16O4 and molecular weight 236.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 6-methoxychromane-3-carboxylate (C13H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
