Chemical Structure
Description
The occurrence of (6-Bromopyrazin-2-yl)methanol is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(6-Bromopyrazin-2-yl)methanol (CAS 1209458-06-9) is a high-purity analytical reference standard with the molecular formula C5H5BrN2O and a molecular weight of 189.01 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, (6-Bromopyrazin-2-yl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 189.01 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (6-Bromopyrazin-2-yl)methanol 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.
