Chemical Structure

tert-Butyl 2-(4-bromophenyl)-3-oxo-1,4,8-triazaspiro[4.5]dec-1-ene-8-carboxylate CAS 2375346-09-9 chemical structure

Description

The occurrence of tert-Butyl 2-(4-bromophenyl)-3-oxo-1,4,8-triazaspiro[4.5]dec-1-ene-8-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

tert-Butyl 2-(4-bromophenyl)-3-oxo-1,4,8-triazaspiro[4.5]dec-1-ene-8-carboxylate (CAS 2375346-09-9), molecular formula C18H22BrN3O3 and molecular weight 408.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, tert-Butyl 2-(4-bromophenyl)-3-oxo-1,4,8-triazaspiro[4.5]dec-1-ene-8-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
