Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl 2-(3-methoxy-3-oxopropyl)pyrrolidine-1-carboxylate 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.
tert-Butyl 2-(3-methoxy-3-oxopropyl)pyrrolidine-1-carboxylate (CAS 190734-68-0), molecular formula C13H23NO4 and molecular weight 257.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl 2-(3-methoxy-3-oxopropyl)pyrrolidine-1-carboxylate (C13H23NO4) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
