Description
As a certified reference material (CRM), (S)-1-Fmoc-2-methyl-piperazine hydrochloride 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.
(S)-1-Fmoc-2-methyl-piperazine hydrochloride (CAS 1187930-89-7), molecular formula C20H22N2O2HCl and molecular weight 358.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-1-Fmoc-2-methyl-piperazine hydrochloride (C20H22N2O2HCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
