Chemical Structure
Description
The molecular framework of Ethyl 4-(2-(azetidin-1-ylmethyl)benzoyl)benzoate (C20H21NO3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Ethyl 4-(2-(azetidin-1-ylmethyl)benzoyl)benzoate (CAS 898754-59-1), molecular formula C20H21NO3 and molecular weight 323.39 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), Ethyl 4-(2-(azetidin-1-ylmethyl)benzoyl)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.
