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 5-chloro-4-iodo-thiochromane.
5-chloro-4-iodo-thiochromane (CAS 1936364-08-7), molecular formula C9H8ClIS and molecular weight 310.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, chlorine/iodine substitution, an aromatic ring system, 5-chloro-4-iodo-thiochromane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-4-iodo-thiochromane 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.
