Chemical Structure

Corosolic Acid CAS 4547-24-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 472.70 g/mol gives Corosolic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Corosolic Acid (CAS 4547-24-4), molecular formula C30H48O4 and molecular weight 472.70 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Corosolic Acid (C30H48O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 472.70 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures Corosolic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
