2-Chloro-N-(3-cyano-6-ethyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)acetamide CAS 551899-66-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-N-(3-cyano-6-ethyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)acetamide.

2-Chloro-N-(3-cyano-6-ethyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)acetamide (CAS 551899-66-2) is a high-purity analytical reference standard with the molecular formula C13H15ClN2OS and a molecular weight of 282.79 g/mol.

2-Chloro-N-(3-cyano-6-ethyl-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)acetamide (C13H15ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
