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 1,1'-(Ethyne-1,2-diyl)bis(cyclohexan-1-ol).
1,1'-(Ethyne-1,2-diyl)bis(cyclohexan-1-ol) (CAS 78-54-6), molecular formula C14H22O2 and molecular weight 222.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1'-(Ethyne-1,2-diyl)bis(cyclohexan-1-ol) (C14H22O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,1'-(Ethyne-1,2-diyl)bis(cyclohexan-1-ol) 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.
