Chemical Structure

Parishin A CAS 62499-28-9 chemical structure

Description

CATO manufactures Parishin A under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Parishin A (CAS 62499-28-9), molecular formula C45H56O25 and molecular weight 996.91 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Parishin A is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 996.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
