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 7-Chloro-1-methyl-1H-indole.
7-Chloro-1-methyl-1H-indole (CAS 620175-78-2), molecular formula C9H8ClN and molecular weight 165.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-Chloro-1-methyl-1H-indole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 7-Chloro-1-methyl-1H-indole 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.
