1-Phenyl-4,5,6,7-tetrahydrotriazolo[4,5-c]pyridine CAS 98175-84-9 chemical structure

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.

1-Phenyl-4,5,6,7-tetrahydrotriazolo[4,5-c]pyridine (CAS 98175-84-9), molecular formula C11H12N4 and molecular weight 200.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Phenyl-4,5,6,7-tetrahydrotriazolo[4,5-c]pyridine (C11H12N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 200.24 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.
