Chemical Structure

Pigment Yellow 180 CAS 77804-81-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Pigment Yellow 180 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 732.70 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).

Pigment Yellow 180 (CAS 77804-81-0) is a high-purity analytical reference standard with the molecular formula C36H32N10O8 and a molecular weight of 732.70 g/mol.

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), Pigment Yellow 180 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.
