Description
Compared with other compounds in its class, the molecular weight of 210.30 g/mol gives 2-Methyl-1-(thiophene-2-carbonyl)piperazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Methyl-1-(thiophene-2-carbonyl)piperazine (CAS 1240581-78-5) is a high-purity analytical reference standard with the molecular formula C10H14N2OS and a molecular weight of 210.30 g/mol.
The molecular framework of 2-Methyl-1-(thiophene-2-carbonyl)piperazine (C10H14N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. 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), 2-Methyl-1-(thiophene-2-carbonyl)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.
