Chemical Structure

3,6-Dimethyloct-4-yne-3,6-diol CAS 78-66-0 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 3,6-Dimethyloct-4-yne-3,6-diol.

3,6-Dimethyloct-4-yne-3,6-diol (CAS 78-66-0), molecular formula C10H18O2 and molecular weight 170.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3,6-Dimethyloct-4-yne-3,6-diol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.25 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.
