Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.66 g/mol gives m-PEG3-Propanoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies m-PEG3-Propanoyl chloride (CAS 66722-87-0), a certified reference material (molecular formula C8H15ClO4, MW 210.66 g/mol) for analytical method development and quality control.
m-PEG3-Propanoyl chloride (C8H15ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), m-PEG3-Propanoyl chloride 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.
