Description
As a certified reference material (CRM), Naphtho[2,3-d][1,3]dioxole-2-thione 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.
Naphtho[2,3-d][1,3]dioxole-2-thione (CAS 67177-41-7), molecular formula C11H6O2S and molecular weight 202.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Naphtho[2,3-d][1,3]dioxole-2-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.23 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.
