Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 498.74 g/mol gives 3B-Acetoxybetulinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3B-Acetoxybetulinic acid (CAS 10376-50-8) is a high-purity analytical reference standard with the molecular formula C32H50O4 and a molecular weight of 498.74 g/mol.
The molecular framework of 3B-Acetoxybetulinic acid (C32H50O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3B-Acetoxybetulinic 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.
