Chemical Structure

3-FLUOROBENZALDEHYDE OXIME CAS 458-02-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3-FLUOROBENZALDEHYDE OXIME (CAS 458-02-6), molecular formula C7H6FNO and molecular weight 139.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-FLUOROBENZALDEHYDE OXIME (C7H6FNO) contains an amide 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 139.13 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
