3-Chloro-n-{3-cyano-4h,5h,6h-cyclopenta[b]thiophen-2-yl}propanamide CAS 732271-45-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-n-{3-cyano-4h,5h,6h-cyclopenta[b]thiophen-2-yl}propanamide.

3-Chloro-n-{3-cyano-4h,5h,6h-cyclopenta[b]thiophen-2-yl}propanamide (CAS 732271-45-3), molecular formula C11H11ClN2OS and molecular weight 254.74 g/mol, is a CATO reference standard with documented purity and traceability.

3-Chloro-n-{3-cyano-4h,5h,6h-cyclopenta[b]thiophen-2-yl}propanamide (C11H11ClN2OS) 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. 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.
