CATO supplies 661472-41-9 BIW199E18V Relamorelin [USAN:INN] UNII-BIW199E18V BIM28131 BIM-28131 Relamorelin 4-Piperidinecarboxamide, 3-benzo(b)thien-3-yl-N-(4-piperidinylcarbonyl)-D-alanyl-D-tryptophyl-L-phenylalanyl-4-amino- Relamorelin [INN] Relamorelin [WHO-DD] RM 131 RM131 RM-131 (CAS 661472-41-9), a certified reference material (molecular formula C43H50N8O5S, MW 790.97 g/mol) for analytical method development and quality control.

661472-41-9 BIW199E18V Relamorelin [USAN:INN] UNII-BIW199E18V BIM28131 BIM-28131 Relamorelin 4-Piperidinecarboxamide, 3-benzo(b)thien-3-yl-N-(4-piperidinylcarbonyl)-D-alanyl-D-tryptophyl-L-phenylalanyl-4-amino- Relamorelin [INN] Relamorelin [WHO-DD] RM 131 RM131 RM-131 (C43H50N8O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

As a certified reference material (CRM), 661472-41-9 BIW199E18V Relamorelin [USAN:INN] UNII-BIW199E18V BIM28131 BIM-28131 Relamorelin 4-Piperidinecarboxamide, 3-benzo(b)thien-3-yl-N-(4-piperidinylcarbonyl)-D-alanyl-D-tryptophyl-L-phenylalanyl-4-amino- Relamorelin [INN] Relamorelin [WHO-DD] RM 131 RM131 RM-131 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.
