Description
As a certified reference material (CRM), 2-Chloro-1-[4-(5,6,7,8-tetrahydronaphthalene-2-sulfonyl)piperazin-1-yl]ethan-1-one 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.
2-Chloro-1-[4-(5,6,7,8-tetrahydronaphthalene-2-sulfonyl)piperazin-1-yl]ethan-1-one (CAS 929973-02-4) is a high-purity analytical reference standard with the molecular formula C16H21ClN2O3S and a molecular weight of 356.87 g/mol.
Structurally, 2-Chloro-1-[4-(5,6,7,8-tetrahydronaphthalene-2-sulfonyl)piperazin-1-yl]ethan-1-one (C16H21ClN2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 356.87 g/mol, it falls into the moderately-high-molecular-weight range. 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.
