2',4'-Dichloro-4-fluoro-[1,1'-biphenyl]-3-ol CAS 1261971-50-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2',4'-Dichloro-4-fluoro-[1,1'-biphenyl]-3-ol.

2',4'-Dichloro-4-fluoro-[1,1'-biphenyl]-3-ol (CAS 1261971-50-9) is a high-purity analytical reference standard with the molecular formula C12H7Cl2FO and a molecular weight of 257.09 g/mol.

Based on its molecular formula C12H7Cl2FO, 2',4'-Dichloro-4-fluoro-[1,1'-biphenyl]-3-ol contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
