Chemical Structure
Description
Di-tert-butyl 4,4'-(pyrimidine-4,6-diylbis(oxy))bis(piperidine-1-carboxylate) (CAS 1353989-70-4), molecular formula C24H38N4O6 and molecular weight 478.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Di-tert-butyl 4,4'-(pyrimidine-4,6-diylbis(oxy))bis(piperidine-1-carboxylate) (C24H38N4O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 478.58 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
