tert-Butyl 2-(methylthio)-4-oxo-3,4,5,6,7,9-hexahydro-8H-pyrimido[4,5-c]azepine-8-carboxylate CAS 2412424-99-6

Description

tert-Butyl 2-(methylthio)-4-oxo-3,4,5,6,7,9-hexahydro-8H-pyrimido[4,5-c]azepine-8-carboxylate (CAS 2412424-99-6) is a high-purity analytical reference standard with the molecular formula C14H21N3O3S and a molecular weight of 311.40 g/mol.

The molecular framework of tert-Butyl 2-(methylthio)-4-oxo-3,4,5,6,7,9-hexahydro-8H-pyrimido[4,5-c]azepine-8-carboxylate (C14H21N3O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), tert-Butyl 2-(methylthio)-4-oxo-3,4,5,6,7,9-hexahydro-8H-pyrimido[4,5-c]azepine-8-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.
