Chemical Structure

Ethyl imidazo[1,2-a]pyridine-2-carboxylate hydrobromide CAS 2549-17-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl imidazo[1,2-a]pyridine-2-carboxylate hydrobromide.

Ethyl imidazo[1,2-a]pyridine-2-carboxylate hydrobromide (CAS 2549-17-9), molecular formula C10H10N2O2HBr and molecular weight 271.11 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl imidazo[1,2-a]pyridine-2-carboxylate hydrobromide (C10H10N2O2HBr) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Ethyl imidazo[1,2-a]pyridine-2-carboxylate hydrobromide 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.
