Chemical Structure
Description
The occurrence of Styrene-2,3,4,5,6-d5 (stabilized with hydroquinone) is closely related to deuterium isotope labeling, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Styrene-2,3,4,5,6-d5 (stabilized with hydroquinone) (CAS 5161-29-5) is a high-purity analytical reference standard with the molecular formula C8H3D5 and a molecular weight of 109.18 g/mol.
The molecular framework of Styrene-2,3,4,5,6-d5 (stabilized with hydroquinone) (C8H3D5) is characterized by deuterium isotope labeling, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Styrene-2,3,4,5,6-d5 (stabilized with hydroquinone) 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.
