Chemical Structure
Description
Owing to a nitrile group, fluorine/chlorine substitution, an aromatic ring system, 5-Chloro-2-fluoroaniline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-Chloro-2-fluoroaniline (CAS 2106-05-0) is a high-purity analytical reference standard with the molecular formula C6H5ClFN and a molecular weight of 145.56 g/mol.
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.
