Rivastigmine USP Related Compound A CAS 32634-68-7 chemical structure

Description

As a certified reference material (CRM), Rivastigmine USP Related Compound 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.

Rivastigmine USP Related Compound A (CAS 32634-68-7) is a high-purity analytical reference standard with the molecular formula C20H18O8 and a molecular weight of 386.35 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Rivastigmine USP Related Compound A is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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