Chemical Structure
Description
The occurrence of HPD-OSu [O-Succinimidyl-1,3-dimethylpropyleneuronium Hexafluorophosphate] is closely related to an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
HPD-OSu [O-Succinimidyl-1,3-dimethylpropyleneuronium Hexafluorophosphate] (CAS 443305-32-6) is a high-purity analytical reference standard with the molecular formula C10H16N3O3F6P and a molecular weight of 371.22 g/mol.
Owing to an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, HPD-OSu [O-Succinimidyl-1,3-dimethylpropyleneuronium Hexafluorophosphate] is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), HPD-OSu [O-Succinimidyl-1,3-dimethylpropyleneuronium Hexafluorophosphate] 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.
