Chemical Structure
Description
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.
6-(tert-Butyl) 8-ethyl (4aR,8S,8aR)-hexahydro-2H-pyrano[3,2-c]pyridine-6,8(5H)-dicarboxylate (CAS 1422344-50-0) is a high-purity analytical reference standard with the molecular formula C16H27NO5 and a molecular weight of 313.39 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 6-(tert-Butyl) 8-ethyl (4aR,8S,8aR)-hexahydro-2H-pyrano[3,2-c]pyridine-6,8(5H)-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
