Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 594.60 g/mol gives Pseudolaric acid B-glucopyranoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pseudolaric acid B-glucopyranoside (CAS 98891-41-9), molecular formula C29H38O13 and molecular weight 594.60 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Pseudolaric acid B-glucopyranoside (C29H38O13) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 594.60 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).
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), Pseudolaric acid B-glucopyranoside 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.
