Chemical Structure

Corynoxidine CAS 57906-85-1 chemical structure

Description

As a certified reference material (CRM), Corynoxidine 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.

Corynoxidine (CAS 57906-85-1), molecular formula C21H25NO5 and molecular weight 371.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Corynoxidine (C21H25NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 371.43 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
