Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methoxy-6,7,8,9-tetrahydro-5H-pyrido[4,3-c]azepine.
3-Methoxy-6,7,8,9-tetrahydro-5H-pyrido[4,3-c]azepine (CAS 1393552-15-2), molecular formula C10H14N2O and molecular weight 178.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Methoxy-6,7,8,9-tetrahydro-5H-pyrido[4,3-c]azepine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
