Chemical Structure

Epinephrine Impurity 36 CAS 5706-85-4 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Epinephrine Impurity 36 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.15 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).

CATO supplies Epinephrine Impurity 36 (CAS 5706-85-4), a pharmacopoeial impurity reference standard (molecular formula C8H8O3, MW 152.15 g/mol) used for the identification and quantification of trace impurities in APIs.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Epinephrine Impurity 36 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.
