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 4-[(Benzenesulfonyl)methyl]-6-[(2-chlorophenyl)sulfanyl]-2-methylpyrimidine.
CATO supplies 4-[(Benzenesulfonyl)methyl]-6-[(2-chlorophenyl)sulfanyl]-2-methylpyrimidine (CAS 338960-50-2), a certified reference material (molecular formula C18H15ClN2O2S2, MW 390.91 g/mol) for analytical method development and quality control.
Structurally, 4-[(Benzenesulfonyl)methyl]-6-[(2-chlorophenyl)sulfanyl]-2-methylpyrimidine (C18H15ClN2O2S2) 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 390.91 g/mol, it falls into the moderately-high-molecular-weight range. 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-[(Benzenesulfonyl)methyl]-6-[(2-chlorophenyl)sulfanyl]-2-methylpyrimidine 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.
