5-Chloro-2-(3-chloro-phenylsulfanyl)-aniline CAS 105836-85-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Chloro-2-(3-chloro-phenylsulfanyl)-aniline.

5-Chloro-2-(3-chloro-phenylsulfanyl)-aniline (CAS 105836-85-9), molecular formula C12H9Cl2NS and molecular weight 270.18 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-Chloro-2-(3-chloro-phenylsulfanyl)-aniline (C12H9Cl2NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 270.18 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 5-Chloro-2-(3-chloro-phenylsulfanyl)-aniline 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.
