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-Amino-6-benzyl-N,N-diethyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide.
3-Amino-6-benzyl-N,N-diethyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (CAS 723748-23-0), molecular formula C20H20F3N3OS and molecular weight 407.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Amino-6-benzyl-N,N-diethyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (C20H20F3N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 407.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
