Chemical Structure

1,8-Octanedithiol CAS 1191-62-4 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 1,8-Octanedithiol.

1,8-Octanedithiol (CAS 1191-62-4), molecular formula C8H18S2 and molecular weight 178.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, 1,8-Octanedithiol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
