Chemical Structure
Description
CATO supplies 4-Chloro-3-cyclohexene-1-carboxylic Acid Methyl Ester (CAS 27705-05-1), a certified reference material (molecular formula C8H11ClO2, MW 174.62 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-3-cyclohexene-1-carboxylic Acid Methyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), 4-Chloro-3-cyclohexene-1-carboxylic Acid Methyl Ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
