Chemical Structure

4-Fluoro-3'-methyl-1,1'-biphenyl CAS 10540-44-0 chemical structure

Description

CATO supplies 4-Fluoro-3'-methyl-1,1'-biphenyl (CAS 10540-44-0), a certified reference material (molecular formula C13H11F, MW 186.22 g/mol) for analytical method development and quality control.

Structurally, 4-Fluoro-3'-methyl-1,1'-biphenyl (C13H11F) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 186.22 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.
