2-((4-Chlorophenyl)thio)thiophene-3-carbaldehyde CAS 306935-23-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4-Chlorophenyl)thio)thiophene-3-carbaldehyde.

2-((4-Chlorophenyl)thio)thiophene-3-carbaldehyde (CAS 306935-23-9), molecular formula C11H7ClOS2 and molecular weight 254.76 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H7ClOS2, 2-((4-Chlorophenyl)thio)thiophene-3-carbaldehyde 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 254.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2-((4-Chlorophenyl)thio)thiophene-3-carbaldehyde 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.
