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 4-Methoxy-1-(methylsulfonyl)-1H-indole.
CATO supplies 4-Methoxy-1-(methylsulfonyl)-1H-indole (CAS 88131-67-3), a certified reference material (molecular formula C10H11NO3S, MW 225.26 g/mol) for analytical method development and quality control.
Structurally, 4-Methoxy-1-(methylsulfonyl)-1H-indole (C10H11NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 225.26 g/mol, it falls into the medium-molecular-weight range. 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.
