Chemical Structure

Aluminium Distearate CAS 300-92-5 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Aluminium Distearate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Aluminium Distearate (CAS 300-92-5), molecular formula C18H35O2HAlO and molecular weight 327.46 g/mol, is a CATO reference standard with documented purity and traceability.

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.
