Chemical Structure

Calyculin A CAS 101932-71-2 chemical structure

Description

As a certified reference material (CRM), Calyculin 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.

Calyculin A (CAS 101932-71-2), molecular formula C50H81N4O15P and molecular weight 1009.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Calyculin A (C50H81N4O15P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 1009.17 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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