Chemical Structure

Desmethyl Nortriptyline CAS 4444-42-2 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 Desmethyl Nortriptyline (CAS 4444-42-2), a certified reference material (molecular formula C18H19N, MW 249.35 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Desmethyl Nortriptyline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Desmethyl Nortriptyline 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.
