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 trans-4-Hydroxycyclohexanecarboxylic Acid Ethyl Ester.
trans-4-Hydroxycyclohexanecarboxylic Acid Ethyl Ester (CAS 3618-04-0), molecular formula C9H16O3 and molecular weight 172.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of trans-4-Hydroxycyclohexanecarboxylic Acid Ethyl Ester (C9H16O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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), trans-4-Hydroxycyclohexanecarboxylic Acid Ethyl 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.
