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-Chloro-1-(1-methyl-2-phenyl-1H-indol-3-yl)-ethanone.
2-Chloro-1-(1-methyl-2-phenyl-1H-indol-3-yl)-ethanone (CAS 721892-15-5) is a high-purity analytical reference standard with the molecular formula C17H14ClNO and a molecular weight of 283.75 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-1-(1-methyl-2-phenyl-1H-indol-3-yl)-ethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 2-Chloro-1-(1-methyl-2-phenyl-1H-indol-3-yl)-ethanone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
