Chemical Structure
Description
The occurrence of Benzo[b]thiophen-2-yl(7,7-dimethyl-6,8-dioxa-2-azaspiro[3.5]nonan-2-yl)methanone is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzo[b]thiophen-2-yl(7,7-dimethyl-6,8-dioxa-2-azaspiro[3.5]nonan-2-yl)methanone (CAS 1396889-07-8) is a high-purity analytical reference standard with the molecular formula C17H19NO3S and a molecular weight of 317.40 g/mol.
The molecular framework of Benzo[b]thiophen-2-yl(7,7-dimethyl-6,8-dioxa-2-azaspiro[3.5]nonan-2-yl)methanone (C17H19NO3S) is characterized by a steroid core, an amide group, a sulfone 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. 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.
As a certified reference material (CRM), Benzo[b]thiophen-2-yl(7,7-dimethyl-6,8-dioxa-2-azaspiro[3.5]nonan-2-yl)methanone 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.
