Chemical Structure
Description
CATO supplies Lofentanil Oxalate (1.0mg/ml in Acetonitrile) (CAS 61380-41-4), a certified reference material (molecular formula C25H32N2O3C2H2O4, MW 498.58 g/mol) for analytical method development and quality control.
Structurally, Lofentanil Oxalate (1.0mg/ml in Acetonitrile) (C25H32N2O3C2H2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 498.58 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Lofentanil Oxalate (1.0mg/ml in Acetonitrile) 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.
