Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Fluoro-5-methyl-2-nitrophenyl)-4-(4-methoxybenzenesulfonyl)piperazine.
CATO supplies 1-(4-Fluoro-5-methyl-2-nitrophenyl)-4-(4-methoxybenzenesulfonyl)piperazine (CAS 1262222-56-9), a certified reference material (molecular formula C18H20FN3O5S, MW 409.43 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(4-Fluoro-5-methyl-2-nitrophenyl)-4-(4-methoxybenzenesulfonyl)piperazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Fluoro-5-methyl-2-nitrophenyl)-4-(4-methoxybenzenesulfonyl)piperazine 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.
