Chemical Structure
Description
The occurrence of 3-Chloro-[1,2,4]triazolo[3,4-a]isoquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Chloro-[1,2,4]triazolo[3,4-a]isoquinoline (CAS 7639-52-3), a certified reference material (molecular formula C10H6ClN3, MW 203.63 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-[1,2,4]triazolo[3,4-a]isoquinoline (C10H6ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
