2,5-Dichloro-4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonic acid CAS 84-57-1

Description

Compared with other compounds in its class, the molecular weight of 323.15 g/mol gives 2,5-Dichloro-4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,5-Dichloro-4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonic acid (CAS 84-57-1), a certified reference material (molecular formula C10H8Cl2N2O4S, MW 323.15 g/mol) for analytical method development and quality control.

2,5-Dichloro-4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonic acid (C10H8Cl2N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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