Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl 2-(pyridin-2-yl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-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-(pyridin-2-yl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate (CAS 1400643-14-2), molecular formula C18H27N3O3 and molecular weight 333.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, tert-Butyl 2-(pyridin-2-yl)-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
