Chemical Structure
Description
As a certified reference material (CRM), N-Deacetyl 10-Demethyl Colchicine 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.
CATO supplies N-Deacetyl 10-Demethyl Colchicine (CAS 3482-37-9), a certified reference material (molecular formula C19H21NO5, MW 343.37 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N-Deacetyl 10-Demethyl Colchicine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
