Chemical Structure
Description
The occurrence of 2-Methyl-5,6-dihydrobenzo[h]quinazoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Methyl-5,6-dihydrobenzo[h]quinazoline (CAS 67602-28-2), a certified reference material (molecular formula C13H12N2, MW 196.25 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methyl-5,6-dihydrobenzo[h]quinazoline (C13H12N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
