Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2-Dimethyl-1,3-dioxolane-4-methanol 4-Methanesulfonate-d5 (CAS 1346604-82-7), molecular formula C7H9D5O5S and molecular weight 215.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2-Dimethyl-1,3-dioxolane-4-methanol 4-Methanesulfonate-d5 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 2,2-Dimethyl-1,3-dioxolane-4-methanol 4-Methanesulfonate-d5 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.
