Chemical Structure
Description
4'-Formyl-[1,1'-biphenyl]-3-carboxylicacid (CAS 222180-20-3), molecular formula C14H10O3 and molecular weight 226.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4'-Formyl-[1,1'-biphenyl]-3-carboxylicacid (C14H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 226.23 g/mol, it falls into the medium-molecular-weight range. 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.
