Chemical Structure
Description
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.
Methyl (S)-4-(pyrrolidin-2-yl)benzoate hydrochloride (CAS 1381929-06-1) is a high-purity analytical reference standard with the molecular formula C12H15NO2HCl and a molecular weight of 241.72 g/mol.
Structurally, Methyl (S)-4-(pyrrolidin-2-yl)benzoate hydrochloride (C12H15NO2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 241.72 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Methyl (S)-4-(pyrrolidin-2-yl)benzoate hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
