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.
CATO supplies Tert-butyl (s)-3-(2-oxo-1,4-dihydroquinazolin-3(2h)-yl)piperidine-1-carboxylate (CAS 1389310-13-7), a certified reference material (molecular formula C18H25N3O3, MW 331.41 g/mol) for analytical method development and quality control.
The molecular framework of Tert-butyl (s)-3-(2-oxo-1,4-dihydroquinazolin-3(2h)-yl)piperidine-1-carboxylate (C18H25N3O3) 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 the protonation state of its nitrogen-containing groups, 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).
As a certified reference material (CRM), Tert-butyl (s)-3-(2-oxo-1,4-dihydroquinazolin-3(2h)-yl)piperidine-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.
