Chemical Structure
Description
4-(Cyclopentylmethyl)piperidine HCl (CAS 188844-20-4), molecular formula C11H21NHCl and molecular weight 203.75 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Cyclopentylmethyl)piperidine HCl (C11H21NHCl) contains 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.
