4'-Fluoroacetophenone CAS 403-42-9

Description

Compared with other compounds in its class, the molecular weight of 138.14 g/mol gives 4'-Fluoroacetophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4'-Fluoroacetophenone (CAS 403-42-9), molecular formula C8H7FO and molecular weight 138.14 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4'-Fluoroacetophenone (C8H7FO) contains 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 138.14 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
