Chemical Structure

Zinc Tosylate CAS 13438-45-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 236.57 g/mol gives Zinc Tosylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Zinc Tosylate (CAS 13438-45-4), molecular formula C7H7O3SZn and molecular weight 236.57 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Zinc Tosylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Zinc Tosylate 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.
