Chemical Structure
Description
2-(2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}ethyl)-4-methyl-1,3-thiazole-5-carboxylic acid (CAS 2092501-01-2), molecular formula C22H20N2O4S and molecular weight 408.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}ethyl)-4-methyl-1,3-thiazole-5-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2-(2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}ethyl)-4-methyl-1,3-thiazole-5-carboxylic acid 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.
