Chemical Structure

Epinephrine Impurity 37 CAS CATO-C4X-184937 chemical structure

Description

The occurrence of Epinephrine Impurity 37 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Epinephrine Impurity 37 (CAS CATO-C4X-184937) is a certified pharmaceutical impurity reference standard with the molecular formula C10H12O4 and a molecular weight of 196.20 g/mol.

Structurally, Epinephrine Impurity 37 (C10H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 196.20 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 37 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.
