trans-4-Heptylcyclohexanecarboxylic acid CAS 38289-31-5

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-Heptylcyclohexanecarboxylic acid.

trans-4-Heptylcyclohexanecarboxylic acid (CAS 38289-31-5), molecular formula C14H26O2 and molecular weight 226.36 g/mol, is a CATO reference standard with documented purity and traceability.

trans-4-Heptylcyclohexanecarboxylic acid (C14H26O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
