5-(5-Oxo-3-palmitamido-4,5-dihydro-1H-pyrazol-1-yl)-2-phenoxybenzenesulfonic acid CAS 94349-41-4 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 5-(5-Oxo-3-palmitamido-4,5-dihydro-1H-pyrazol-1-yl)-2-phenoxybenzenesulfonic acid.

CATO supplies 5-(5-Oxo-3-palmitamido-4,5-dihydro-1H-pyrazol-1-yl)-2-phenoxybenzenesulfonic acid (CAS 94349-41-4), a certified reference material (molecular formula C31H43N3O6S, MW 585.75 g/mol) for analytical method development and quality control.

Structurally, 5-(5-Oxo-3-palmitamido-4,5-dihydro-1H-pyrazol-1-yl)-2-phenoxybenzenesulfonic acid (C31H43N3O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 585.75 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 5-(5-Oxo-3-palmitamido-4,5-dihydro-1H-pyrazol-1-yl)-2-phenoxybenzenesulfonic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
