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-1-yl hydroxycarbamate (CAS 31335-33-8), a certified reference material (molecular formula C11H9NO3, MW 203.19 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Naphthalen-1-yl hydroxycarbamate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.19 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-1-yl hydroxycarbamate 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.
