Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4'-(Tert-butyl)-5-fluoro-[1,1'-biphenyl]-2-carboxylic acid.
4'-(Tert-butyl)-5-fluoro-[1,1'-biphenyl]-2-carboxylic acid (CAS 926200-09-1) is a high-purity analytical reference standard with the molecular formula C17H17FO2 and a molecular weight of 272.31 g/mol.
4'-(Tert-butyl)-5-fluoro-[1,1'-biphenyl]-2-carboxylic acid (C17H17FO2) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
