Chemical Structure
Description
The molecular framework of 4-(Pyrrolidine-1-carbonyl)benzyl benzoate (C19H19NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4-(Pyrrolidine-1-carbonyl)benzyl benzoate (CAS 661486-92-6) is a high-purity analytical reference standard with the molecular formula C19H19NO3 and a molecular weight of 309.36 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(Pyrrolidine-1-carbonyl)benzyl benzoate 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.
