Chemical Structure

Ethyl 2-[(3-nitropyridin-2-yl)sulfonyl]acetate CAS 1774901-38-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.25 g/mol gives Ethyl 2-[(3-nitropyridin-2-yl)sulfonyl]acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-[(3-nitropyridin-2-yl)sulfonyl]acetate (CAS 1774901-38-0), molecular formula C9H10N2O6S and molecular weight 274.25 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 2-[(3-nitropyridin-2-yl)sulfonyl]acetate (C9H10N2O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
