Chemical Structure

n-Heptadecylcyclohexane CAS 19781-73-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-Heptadecylcyclohexane.

CATO supplies n-Heptadecylcyclohexane (CAS 19781-73-8), a certified reference material (molecular formula C23H46, MW 322.61 g/mol) for analytical method development and quality control.

Owing to an organic framework, n-Heptadecylcyclohexane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.61 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.

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.
