Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2-Chlorophenyl)-2-thiophenecarbaldehyde.
CATO supplies 4-(2-Chlorophenyl)-2-thiophenecarbaldehyde (CAS 893736-76-0), a certified reference material (molecular formula C11H7ClOS, MW 222.69 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H7ClOS, 4-(2-Chlorophenyl)-2-thiophenecarbaldehyde contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-(2-Chlorophenyl)-2-thiophenecarbaldehyde 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.
