Chemical Structure

2-Methylpentacosane CAS 629-87-8 chemical structure

Description

The occurrence of 2-Methylpentacosane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Methylpentacosane (CAS 629-87-8), molecular formula C26H54 and molecular weight 366.71 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methylpentacosane (C26H54) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
