Chemical Structure

2-(4-nitro­phenyl­)-ethyl­tosyl­ate CAS 6948-72-7 chemical structure

Description

As a certified reference material (CRM), 2-(4-nitro­phenyl­)-ethyl­tosyl­ate 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.

2-(4-nitro­phenyl­)-ethyl­tosyl­ate (CAS 6948-72-7), molecular formula C15H15NO5S and molecular weight 321.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(4-nitro­phenyl­)-ethyl­tosyl­ate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.35 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.
