Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5'-Cyano-2'-fluoro-2-methyl-[1,1'-biphenyl]-4-carboxylic acid (CAS 1262006-23-4), a certified reference material (molecular formula C15H10FNO2, MW 255.24 g/mol) for analytical method development and quality control.
Structurally, 5'-Cyano-2'-fluoro-2-methyl-[1,1'-biphenyl]-4-carboxylic acid (C15H10FNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 255.24 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
