Chemical Structure
Description
The occurrence of Palmostatin A is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Palmostatin A (CAS 1233365-08-6), a certified reference material (molecular formula C23H36O4, MW 376.53 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, Palmostatin A is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.53 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
