Chemical Structure

5-(O-tolyl)pyrazin-2-ol CAS 1159818-46-8 chemical structure

Description

The occurrence of 5-(O-tolyl)pyrazin-2-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(O-tolyl)pyrazin-2-ol (CAS 1159818-46-8) is a high-purity analytical reference standard with the molecular formula C11H10N2O and a molecular weight of 186.21 g/mol.

5-(O-tolyl)pyrazin-2-ol (C11H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
