Chemical Structure
Description
CATO supplies (±)-WB 4101 (hydrochloride) (CAS 2170-58-3), a certified reference material (molecular formula C19H23NO5HCl, MW 381.85 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (±)-WB 4101 (hydrochloride) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (±)-WB 4101 (hydrochloride) 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.
