Chemical Structure
Description
4-(3,5-Dichlorophenyl)-2-(trifluoromethyl)pyridin-3-ol (CAS 1361880-20-7) is a high-purity analytical reference standard with the molecular formula C12H6Cl2F3NO and a molecular weight of 308.08 g/mol.
Structurally, 4-(3,5-Dichlorophenyl)-2-(trifluoromethyl)pyridin-3-ol (C12H6Cl2F3NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 308.08 g/mol, it falls into the moderately-high-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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
