tert-Butyl ((8-bromo-6-fluoro-2,2-dimethylchroman-4-yl)methyl)carbamate CAS 1956322-89-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 388.27 g/mol gives tert-Butyl ((8-bromo-6-fluoro-2,2-dimethylchroman-4-yl)methyl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl ((8-bromo-6-fluoro-2,2-dimethylchroman-4-yl)methyl)carbamate (CAS 1956322-89-6) is a high-purity analytical reference standard with the molecular formula C17H23BrFNO3 and a molecular weight of 388.27 g/mol.

The molecular framework of tert-Butyl ((8-bromo-6-fluoro-2,2-dimethylchroman-4-yl)methyl)carbamate (C17H23BrFNO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 ((8-bromo-6-fluoro-2,2-dimethylchroman-4-yl)methyl)carbamate 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.
