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 17-(tert-Butoxy)-17-oxoheptadecanoic acid.
17-(tert-Butoxy)-17-oxoheptadecanoic acid (CAS 905302-44-5), molecular formula C21H40O4 and molecular weight 356.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 17-(tert-Butoxy)-17-oxoheptadecanoic acid (C21H40O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
