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-Chloro-2-methylaniline.
4-Chloro-2-methylaniline (CAS 95-69-2) is a high-purity analytical reference standard with the molecular formula C7H8ClN and a molecular weight of 141.60 g/mol.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 4-Chloro-2-methylaniline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-Chloro-2-methylaniline 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.
