Chemical Structure

Equilin 3-Benzoate CAS 6030-80-4 chemical structure

Description

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.

Equilin 3-Benzoate (CAS 6030-80-4), molecular formula C25H24O3 and molecular weight 372.46 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C25H24O3, Equilin 3-Benzoate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 372.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Equilin 3-Benzoate 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.
