1-(tert-Butyl) 4-ethyl (R)-5-hydroxy-2-methyl-3,6-dihydropyridine-1,4(2H)-dicarboxylate CAS 2764670-70-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(tert-Butyl) 4-ethyl (R)-5-hydroxy-2-methyl-3,6-dihydropyridine-1,4(2H)-dicarboxylate.

1-(tert-Butyl) 4-ethyl (R)-5-hydroxy-2-methyl-3,6-dihydropyridine-1,4(2H)-dicarboxylate (CAS 2764670-70-2), molecular formula C14H23NO5 and molecular weight 285.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(tert-Butyl) 4-ethyl (R)-5-hydroxy-2-methyl-3,6-dihydropyridine-1,4(2H)-dicarboxylate (C14H23NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 285.34 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
