Chemical Structure
Description
The occurrence of 3-(2-Chlorophenoxy)pyrazine-2-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(2-Chlorophenoxy)pyrazine-2-carboxylic acid (CAS 1228551-81-2) is a high-purity analytical reference standard with the molecular formula C11H7ClN2O3 and a molecular weight of 250.64 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2-Chlorophenoxy)pyrazine-2-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.64 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).
