N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-(thieno[2,3-d]pyrimidin-4-yloxy)acetamide CAS 756857-71-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-(thieno[2,3-d]pyrimidin-4-yloxy)acetamide.

N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-(thieno[2,3-d]pyrimidin-4-yloxy)acetamide (CAS 756857-71-3) is a high-purity analytical reference standard with the molecular formula C16H13N3O4S and a molecular weight of 343.36 g/mol.

N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-(thieno[2,3-d]pyrimidin-4-yloxy)acetamide (C16H13N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-(thieno[2,3-d]pyrimidin-4-yloxy)acetamide 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.
