Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 168.16 g/mol gives Methyl 2-Fluoro-5-methylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 2-Fluoro-5-methylbenzoate (CAS 2967-93-3), a certified reference material (molecular formula C9H9FO2, MW 168.16 g/mol) for analytical method development and quality control.
Structurally, Methyl 2-Fluoro-5-methylbenzoate (C9H9FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 168.16 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
