Chemical Structure
Description
As a certified reference material (CRM), Methyl 3-[(4-chlorophenyl)sulfonylmethyl]benzoate 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.
CATO supplies Methyl 3-[(4-chlorophenyl)sulfonylmethyl]benzoate (CAS 143427-34-3), a certified reference material (molecular formula C15H13ClO4S, MW 324.78 g/mol) for analytical method development and quality control.
Structurally, Methyl 3-[(4-chlorophenyl)sulfonylmethyl]benzoate (C15H13ClO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 324.78 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.
