Chemical Structure
Description
As a certified reference material (CRM), Methyl 3'-(ethylsulfonyl)-4-methyl-5-nitrobiphenyl-3-carboxylate 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.
Methyl 3'-(ethylsulfonyl)-4-methyl-5-nitrobiphenyl-3-carboxylate (CAS 1005499-49-9) is a high-purity analytical reference standard with the molecular formula C17H17NO6S and a molecular weight of 363.38 g/mol.
The molecular framework of Methyl 3'-(ethylsulfonyl)-4-methyl-5-nitrobiphenyl-3-carboxylate (C17H17NO6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
