Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 192.21 g/mol gives Methyl 3-cyclopropoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 3-cyclopropoxybenzoate (CAS 921602-60-0), molecular formula C11H12O3 and molecular weight 192.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-cyclopropoxybenzoate (C11H12O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
