1,3-Benzenedisulfonic acid, diethyl ester CAS 34577-48-5

Description

Compared with other compounds in its class, the molecular weight of 294.34 g/mol gives 1,3-Benzenedisulfonic acid, diethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,3-Benzenedisulfonic acid, diethyl ester (CAS 34577-48-5), a certified reference material (molecular formula C10H14O6S2, MW 294.34 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1,3-Benzenedisulfonic acid, diethyl ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.34 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).

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), 1,3-Benzenedisulfonic acid, diethyl ester 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.
