Chemical Structure

2,3:4,5-Di-O-isopropylidene-L-arabitol, 98% CAS 84709-35-3 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 2,3:4,5-Di-O-isopropylidene-L-arabitol, 98%.

2,3:4,5-Di-O-isopropylidene-L-arabitol, 98% (CAS 84709-35-3), molecular formula C11H20O5 and molecular weight 232.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,3:4,5-Di-O-isopropylidene-L-arabitol, 98% is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.27 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), 2,3:4,5-Di-O-isopropylidene-L-arabitol, 98% 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.
