Chemical Structure
Description
1-((4-Chlorophenyl)sulfonyl)-N'-(4-methylbenzoyl)piperidine-4-carbohydrazide (CAS 477872-85-8) is a high-purity analytical reference standard with the molecular formula C20H22ClN3O4S and a molecular weight of 435.92 g/mol.
1-((4-Chlorophenyl)sulfonyl)-N'-(4-methylbenzoyl)piperidine-4-carbohydrazide (C20H22ClN3O4S) contains a flavonoid core, 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.
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), 1-((4-Chlorophenyl)sulfonyl)-N'-(4-methylbenzoyl)piperidine-4-carbohydrazide 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.
