Chemical Structure

5-Chloro-1,1a,6,6a-tetrahydrocyclopropa[a]indene-1-carboxylic acid CAS 2044773-47-7 chemical structure

Description

CATO supplies 5-Chloro-1,1a,6,6a-tetrahydrocyclopropa[a]indene-1-carboxylic acid (CAS 2044773-47-7), a certified reference material (molecular formula C11H9ClO2, MW 208.64 g/mol) for analytical method development and quality control.

The molecular framework of 5-Chloro-1,1a,6,6a-tetrahydrocyclopropa[a]indene-1-carboxylic acid (C11H9ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 5-Chloro-1,1a,6,6a-tetrahydrocyclopropa[a]indene-1-carboxylic acid 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.
