Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 610.95 g/mol gives Chlorophyll c1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Chlorophyll c1 (CAS 18901-56-9), molecular formula C35H30N4O5Mg and molecular weight 610.95 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Chlorophyll c1 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 610.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Chlorophyll c1 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.
