Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dimethyl 2-(2-(azepan-1-yl)acetamido)terephthalate oxalate.
Dimethyl 2-(2-(azepan-1-yl)acetamido)terephthalate oxalate (CAS 1215800-84-2), molecular formula C18H24N2O5C2H2O4 and molecular weight 438.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dimethyl 2-(2-(azepan-1-yl)acetamido)terephthalate oxalate (C18H24N2O5C2H2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 438.43 g/mol, it falls into the moderately-high-molecular-weight range. 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.
