2-((4-Chlorophenyl)thio)-4-methyl-3-(methylsulfonyl)-6-phenylpyridine CAS 339017-08-2

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)-4-methyl-3-(methylsulfonyl)-6-phenylpyridine.

2-((4-Chlorophenyl)thio)-4-methyl-3-(methylsulfonyl)-6-phenylpyridine (CAS 339017-08-2), molecular formula C19H16ClNO2S2 and molecular weight 389.92 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-((4-Chlorophenyl)thio)-4-methyl-3-(methylsulfonyl)-6-phenylpyridine (C19H16ClNO2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 389.92 g/mol, it falls into the moderately-high-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), 2-((4-Chlorophenyl)thio)-4-methyl-3-(methylsulfonyl)-6-phenylpyridine 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.
