Chemical Structure
Description
1,4-Dimethoxy-10,11-dihydro-5-azatetraphene (CAS 146830-15-1), molecular formula C19H17NO2 and molecular weight 291.34 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H17NO2, 1,4-Dimethoxy-10,11-dihydro-5-azatetraphene contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
