Chemical Structure
Description
The occurrence of 3-Pyrrolidinecarboxylic acid, 3-phenyl-1-(phenylmethyl)-, methyl ester, hydrochloride (1:1) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Pyrrolidinecarboxylic acid, 3-phenyl-1-(phenylmethyl)-, methyl ester, hydrochloride (1:1) (CAS 1955499-22-5), molecular formula C19H21NO2HCl and molecular weight 331.84 g/mol, is a CATO reference standard with documented purity and traceability.
3-Pyrrolidinecarboxylic acid, 3-phenyl-1-(phenylmethyl)-, methyl ester, hydrochloride (1:1) (C19H21NO2HCl) contains a steroid core, 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, the carboxyl group imparts weak acidity; 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.
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.
