Chemical Structure

1,2-Diacetin CAS 102-62-5 chemical structure

Description

The occurrence of 1,2-Diacetin is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-Diacetin (CAS 102-62-5), molecular formula C7H12O5 and molecular weight 176.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,2-Diacetin is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.17 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), 1,2-Diacetin 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.
