Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Propyl 2-amino-5,6,7,8-tetrahydro-4H-cyclohepta-[b]thiophene-3-carboxylate.
CATO supplies Propyl 2-amino-5,6,7,8-tetrahydro-4H-cyclohepta-[b]thiophene-3-carboxylate (CAS 351982-19-9), a certified reference material (molecular formula C13H19NO2S, MW 253.36 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H19NO2S, Propyl 2-amino-5,6,7,8-tetrahydro-4H-cyclohepta-[b]thiophene-3-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Propyl 2-amino-5,6,7,8-tetrahydro-4H-cyclohepta-[b]thiophene-3-carboxylate 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.
