4-[(4-chlorophenyl)methyl]-4H-thieno[3,2-b]pyrrole-5-carboxylic acid 924643-46-9 NS-04875 CAS 924643-46-9 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 4-[(4-chlorophenyl)methyl]-4H-thieno[3,2-b]pyrrole-5-carboxylic acid 924643-46-9 NS-04875.

4-[(4-chlorophenyl)methyl]-4H-thieno[3,2-b]pyrrole-5-carboxylic acid 924643-46-9 NS-04875 (CAS 924643-46-9) is a high-purity analytical reference standard with the molecular formula C14H10ClNO2S and a molecular weight of 291.75 g/mol.

4-[(4-chlorophenyl)methyl]-4H-thieno[3,2-b]pyrrole-5-carboxylic acid 924643-46-9 NS-04875 (C14H10ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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, the carboxyl group imparts weak acidity; 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.

As a certified reference material (CRM), 4-[(4-chlorophenyl)methyl]-4H-thieno[3,2-b]pyrrole-5-carboxylic acid 924643-46-9 NS-04875 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
