2-Amino-5,5,7,7-tetramethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxamide CAS 1654726-92-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-5,5,7,7-tetramethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxamide.

CATO supplies 2-Amino-5,5,7,7-tetramethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxamide (CAS 1654726-92-7), a certified reference material (molecular formula C12H18N2O2S, MW 254.35 g/mol) for analytical method development and quality control.

The molecular framework of 2-Amino-5,5,7,7-tetramethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxamide (C12H18N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-Amino-5,5,7,7-tetramethyl-4,7-dihydro-5H-thieno[2,3-c]pyran-3-carboxamide 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.
