2-Bromo-4-chloro-N-(1-methylpyrrolidin-2-ylidene)aniline CAS 27033-89-2 chemical structure

Description

CATO manufactures 2-Bromo-4-chloro-N-(1-methylpyrrolidin-2-ylidene)aniline 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.

CATO supplies 2-Bromo-4-chloro-N-(1-methylpyrrolidin-2-ylidene)aniline (CAS 27033-89-2), a certified reference material (molecular formula C11H12BrClN2, MW 287.58 g/mol) for analytical method development and quality control.

Structurally, 2-Bromo-4-chloro-N-(1-methylpyrrolidin-2-ylidene)aniline (C11H12BrClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. 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 287.58 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.

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.
