Description

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.

9-Methyl-7,8,9,10-tetrahydropyrazino[1,2-b]indazol-1(2H)-one (CAS 1708428-06-1) is a high-purity analytical reference standard with the molecular formula C11H13N3O and a molecular weight of 203.24 g/mol.

Structurally, 9-Methyl-7,8,9,10-tetrahydropyrazino[1,2-b]indazol-1(2H)-one (C11H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 203.24 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
