Chemical Structure

Chlorophyll A CAS 479-61-8 chemical structure

Description

As a certified reference material (CRM), Chlorophyll A 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.

Chlorophyll A (CAS 479-61-8), molecular formula C55H72N4O5Mg and molecular weight 893.51 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Chlorophyll A (C55H72N4O5Mg) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 893.51 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
