4-(5-Chloropentanoyl)benzonitrile CAS 210962-46-2

Description

Compared with other compounds in its class, the molecular weight of 221.68 g/mol gives 4-(5-Chloropentanoyl)benzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(5-Chloropentanoyl)benzonitrile (CAS 210962-46-2), molecular formula C12H12ClNO and molecular weight 221.68 g/mol, is a CATO reference standard with documented purity and traceability.

4-(5-Chloropentanoyl)benzonitrile (C12H12ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
