Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (e)-3-(6-Methylimidazo[2,1-b]thiazol-5-yl)acrylic acid.
CATO supplies (e)-3-(6-Methylimidazo[2,1-b]thiazol-5-yl)acrylic acid (CAS 133891-36-8), a certified reference material (molecular formula C9H8N2O2S, MW 208.24 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (e)-3-(6-Methylimidazo[2,1-b]thiazol-5-yl)acrylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.24 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).
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), (e)-3-(6-Methylimidazo[2,1-b]thiazol-5-yl)acrylic 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.
