Chemical Structure
Description
As a certified reference material (CRM), (R)-Butane-1,2-diol 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.
(R)-Butane-1,2-diol (CAS 40348-66-1), molecular formula C4H10O2 and molecular weight 90.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (R)-Butane-1,2-diol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 90.12 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.
