Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-{[(4-chlorophenyl)sulfanyl]methyl}-1H-1,3-benzimidazol-1-yl)-N-methyl-N-phenylacetamide.
2-(2-{[(4-chlorophenyl)sulfanyl]methyl}-1H-1,3-benzimidazol-1-yl)-N-methyl-N-phenylacetamide (CAS 339100-22-0), molecular formula C23H20ClN3OS and molecular weight 421.94 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-{[(4-chlorophenyl)sulfanyl]methyl}-1H-1,3-benzimidazol-1-yl)-N-methyl-N-phenylacetamide (C23H20ClN3OS) contains a steroid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2-(2-{[(4-chlorophenyl)sulfanyl]methyl}-1H-1,3-benzimidazol-1-yl)-N-methyl-N-phenylacetamide 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.
