Chemical Structure

Sodium 4-(3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate CAS 23215-04-5 chemical structure

Description

The occurrence of Sodium 4-(3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium 4-(3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate (CAS 23215-04-5), molecular formula C10H9N2O4SNa and molecular weight 276.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium 4-(3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Sodium 4-(3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)benzenesulfonate 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.
