Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 246.65 g/mol gives Ethyl 2-(3-nitropyridin-2-yl)acetate hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-(3-nitropyridin-2-yl)acetate hydrochloride (CAS 178896-74-7) is a high-purity analytical reference standard with the molecular formula C9H10N2O4HCl and a molecular weight of 246.65 g/mol.
Ethyl 2-(3-nitropyridin-2-yl)acetate hydrochloride (C9H10N2O4HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 2-(3-nitropyridin-2-yl)acetate hydrochloride 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.
