Chemical Structure

tert-Butyl 4-methoxy-1,1-dimethyl-1,2-dihydrobenzo[d][1,3]azasiline-3(4H)-carboxylate CAS 2222440-68-6 chemical structure

Description

The occurrence of tert-Butyl 4-methoxy-1,1-dimethyl-1,2-dihydrobenzo[d][1,3]azasiline-3(4H)-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-Butyl 4-methoxy-1,1-dimethyl-1,2-dihydrobenzo[d][1,3]azasiline-3(4H)-carboxylate (CAS 2222440-68-6), molecular formula C16H25NO3Si and molecular weight 307.46 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of tert-Butyl 4-methoxy-1,1-dimethyl-1,2-dihydrobenzo[d][1,3]azasiline-3(4H)-carboxylate (C16H25NO3Si) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 4-methoxy-1,1-dimethyl-1,2-dihydrobenzo[d][1,3]azasiline-3(4H)-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.
