Chemical Structure

1-Dodecanethiol CAS 112-55-0 chemical structure

Description

The occurrence of 1-Dodecanethiol is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Dodecanethiol (CAS 112-55-0), molecular formula C12H26S and molecular weight 202.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Dodecanethiol (C12H26S) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 202.40 g/mol, it falls into the medium-molecular-weight range. 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.
