Chemical Structure
Description
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.
CATO supplies 8-chloro-1,4,5,7,12-pentaazatricyclo[7.3.0.0²,⁶]dodeca-2(6),3,7,9,11-pentaene (CAS 2706602-35-7), a certified reference material (molecular formula C7H4ClN5, MW 193.59 g/mol) for analytical method development and quality control.
The molecular framework of 8-chloro-1,4,5,7,12-pentaazatricyclo[7.3.0.0²,⁶]dodeca-2(6),3,7,9,11-pentaene (C7H4ClN5) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
