Chemical Structure
Description
The occurrence of Vinyl-d3 Bromide (gas) (stabilized with hydroquinone) is closely related to deuterium isotope labeling, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Vinyl-d3 Bromide (gas) (stabilized with hydroquinone) (CAS 4666-78-8) is a high-purity analytical reference standard with the molecular formula C2D3Br and a molecular weight of 109.97 g/mol.
Owing to deuterium isotope labeling, bromine substitution, Vinyl-d3 Bromide (gas) (stabilized with hydroquinone) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 109.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Vinyl-d3 Bromide (gas) (stabilized with hydroquinone) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
