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 Ethyl 4,4-difluoro-6,6-dimethyltetrahydro-2H-pyran-2-carboxylate.
Ethyl 4,4-difluoro-6,6-dimethyltetrahydro-2H-pyran-2-carboxylate (CAS 2791313-71-6), molecular formula C10H16F2O3 and molecular weight 222.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 4,4-difluoro-6,6-dimethyltetrahydro-2H-pyran-2-carboxylate (C10H16F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Ethyl 4,4-difluoro-6,6-dimethyltetrahydro-2H-pyran-2-carboxylate 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.
