Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-amino-6-tert-butyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate.

Ethyl 2-amino-6-tert-butyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (CAS 351980-73-9), molecular formula C15H23NO2S and molecular weight 281.41 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 2-amino-6-tert-butyl-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxylate (C15H23NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 281.41 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
