Chemical Structure

1-Octadecanethiol CAS 2885-00-9 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 1-Octadecanethiol.

1-Octadecanethiol (CAS 2885-00-9) is a high-purity analytical reference standard with the molecular formula C18H38S and a molecular weight of 286.56 g/mol.

Owing to sulfur-containing functionality, 1-Octadecanethiol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.56 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.

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.
