Chemical Structure

7-((tert-Butyldimethylsilyl)oxy)heptanoic acid CAS 77744-45-7 chemical structure

Description

The occurrence of 7-((tert-Butyldimethylsilyl)oxy)heptanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-((tert-Butyldimethylsilyl)oxy)heptanoic acid (CAS 77744-45-7), molecular formula C13H28O3Si and molecular weight 260.45 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 7-((tert-Butyldimethylsilyl)oxy)heptanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 7-((tert-Butyldimethylsilyl)oxy)heptanoic 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.
