Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(Ethoxycarbonyl)spiro[3.3]heptane-2-carboxylic acid.
6-(Ethoxycarbonyl)spiro[3.3]heptane-2-carboxylic acid (CAS 28114-90-1), molecular formula C11H16O4 and molecular weight 212.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(Ethoxycarbonyl)spiro[3.3]heptane-2-carboxylic acid (C11H16O4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 6-(Ethoxycarbonyl)spiro[3.3]heptane-2-carboxylic acid 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.
