Chemical Structure
Description
The occurrence of 3,5-Dibromopyridine-d3 is closely related to deuterium isotope labeling, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Dibromopyridine-d3 (CAS 1219799-05-9), a certified reference material (molecular formula C5D3Br2N, MW 239.91 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a nitrile group, bromine substitution, 3,5-Dibromopyridine-d3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3,5-Dibromopyridine-d3 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.
