Chemical Structure
Description
The occurrence of 4-(2-Pyrrolidin-1-ylethoxy)benzoic acid;hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(2-Pyrrolidin-1-ylethoxy)benzoic acid;hydrochloride (CAS 63675-90-1), a certified reference material (molecular formula C13H17NO3HCl, MW 271.74 g/mol) for analytical method development and quality control.
The molecular framework of 4-(2-Pyrrolidin-1-ylethoxy)benzoic acid;hydrochloride (C13H17NO3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
