Chemical Structure

C.I. Acid green 27 CAS 6408-57-7 chemical structure

Description

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

C.I. Acid green 27 (CAS 6408-57-7), molecular formula C34H32N2O8S2Na and molecular weight 683.75 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, C.I. Acid green 27 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 683.75 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).

CATO manufactures C.I. Acid green 27 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.
