Compared with other compounds in its class, the molecular weight of 180.11 g/mol gives Pentaric acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pentaric acid (CAS 488-31-3), a certified reference material (molecular formula C5H8O7, MW 180.11 g/mol) for analytical method development and quality control.
Pentaric acid (C5H8O7) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), Pentaric acid 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.
