Chemical Structure
Description
CATO supplies (24S)-Cycloartane-3,24,25-triol 24,25-acetonide (CAS 57576-31-5), a certified reference material (molecular formula C33H56O3, MW 500.80 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (24S)-Cycloartane-3,24,25-triol 24,25-acetonide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.80 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), (24S)-Cycloartane-3,24,25-triol 24,25-acetonide 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.
