Chemical Structure

1-mercapto-2-propanol CAS 1068-47-9 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-mercapto-2-propanol.

1-mercapto-2-propanol (CAS 1068-47-9) is a high-purity analytical reference standard with the molecular formula C3H8OS and a molecular weight of 92.16 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-mercapto-2-propanol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 92.16 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.
