Chemical Structure

Naphthalen-2-yl-acetyl chloride CAS 37859-25-9 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.

CATO supplies Naphthalen-2-yl-acetyl chloride (CAS 37859-25-9), a certified reference material (molecular formula C12H9ClO, MW 204.65 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Naphthalen-2-yl-acetyl chloride is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.65 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).

As a certified reference material (CRM), Naphthalen-2-yl-acetyl chloride 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.
