6-Methoxyimidazo[1,2-a]pyrazine-3-carboxylic acid CAS 1554409-07-2

Description

Compared with other compounds in its class, the molecular weight of 193.16 g/mol gives 6-Methoxyimidazo[1,2-a]pyrazine-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Methoxyimidazo[1,2-a]pyrazine-3-carboxylic acid (CAS 1554409-07-2) is a high-purity analytical reference standard with the molecular formula C8H7N3O3 and a molecular weight of 193.16 g/mol.

The molecular framework of 6-Methoxyimidazo[1,2-a]pyrazine-3-carboxylic acid (C8H7N3O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
