Alisol B CAS 18649-93-9 chemical structure

Description

Alisol B (CAS 18649-93-9) is a high-purity analytical reference standard with the molecular formula C30H48O4 and a molecular weight of 472.70 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Alisol B is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 472.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Alisol B 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.
