(Z)-2-(benzo[d]thiazol-2-yl)-4-(1-((2-hydroxyethyl)amino)ethylidene)-5-methyl-2,4-dihydro-3H-pyrazol-3-one (CAS 299443-56-4) is a high-purity analytical reference standard with the molecular formula C15H16N4O2S and a molecular weight of 316.38 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (Z)-2-(benzo[d]thiazol-2-yl)-4-(1-((2-hydroxyethyl)amino)ethylidene)-5-methyl-2,4-dihydro-3H-pyrazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.38 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.
CATO manufactures (Z)-2-(benzo[d]thiazol-2-yl)-4-(1-((2-hydroxyethyl)amino)ethylidene)-5-methyl-2,4-dihydro-3H-pyrazol-3-one 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.
