Chemical Structure
Description
2-(5-Chloro-2-hydroxybenzoyl)-N-methylhydrazinecarbothioamide (CAS 891055-71-3) is a high-purity analytical reference standard with the molecular formula C9H10ClN3O2S and a molecular weight of 259.71 g/mol.
2-(5-Chloro-2-hydroxybenzoyl)-N-methylhydrazinecarbothioamide (C9H10ClN3O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-(5-Chloro-2-hydroxybenzoyl)-N-methylhydrazinecarbothioamide 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.
