Chemical Structure

(R,Z)-Methyl 7-(3-hydroxy-5-oxocyclopent-1-en-1-yl)hept-5-enoate CAS 42541-96-8 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 (R,Z)-Methyl 7-(3-hydroxy-5-oxocyclopent-1-en-1-yl)hept-5-enoate.

CATO supplies (R,Z)-Methyl 7-(3-hydroxy-5-oxocyclopent-1-en-1-yl)hept-5-enoate (CAS 42541-96-8), a certified reference material (molecular formula C13H18O4, MW 238.28 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (R,Z)-Methyl 7-(3-hydroxy-5-oxocyclopent-1-en-1-yl)hept-5-enoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.28 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), (R,Z)-Methyl 7-(3-hydroxy-5-oxocyclopent-1-en-1-yl)hept-5-enoate 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.
