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-Butanethiol.
1-Butanethiol (CAS 109-79-5), molecular formula C4H10S and molecular weight 90.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, 1-Butanethiol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 90.19 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.
As a certified reference material (CRM), 1-Butanethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
