Chemical Structure
Description
Tert-butyl 2'-oxo-1',2'-dihydrospiro[piperidine-4,3'-pyrrolo[3,2-b]pyridine]-1-carboxylate (CAS 1290625-80-7), molecular formula C16H21N3O3 and molecular weight 303.36 g/mol, is a CATO reference standard with documented purity and traceability.
Tert-butyl 2'-oxo-1',2'-dihydrospiro[piperidine-4,3'-pyrrolo[3,2-b]pyridine]-1-carboxylate (C16H21N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Tert-butyl 2'-oxo-1',2'-dihydrospiro[piperidine-4,3'-pyrrolo[3,2-b]pyridine]-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.
