Chemical Structure
Description
Based on its molecular formula C10H12N2O, 2-(6-Methyl-3,4-dihydropyrrolo[1,2-a]pyrazin-1(2H)-ylidene)acetaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 176.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-(6-Methyl-3,4-dihydropyrrolo[1,2-a]pyrazin-1(2H)-ylidene)acetaldehyde (CAS 345892-02-6), molecular formula C10H12N2O and molecular weight 176.22 g/mol, is a CATO reference standard with documented purity and traceability.
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.
