Chemical Structure

Bafilomycin A1 CAS 88899-55-2 chemical structure

Description

Bafilomycin A1 (CAS 88899-55-2), molecular formula C35H58O9 and molecular weight 622.83 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Bafilomycin A1 is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 622.83 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), Bafilomycin A1 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.
