Product Description

Product Description

Hexadecyl diacid mono-tert-butyl ester (Boc-C14-C0OH) is an important chemical substance, mainly used in the synthesis of antibody drug conjugates (ADC) and PROTAC linkers.
Basic information
Chemical formula: C20H3804 Molecular weight: 341.50500
Appearance: White off-white crystals-powder Melting point: 58.0-62.0°C
Density: 0.959±0.06g/cm3
Solubility: Insoluble in water (2.9E-3 g/L at 25°C) 12 Uses
ADC linker: Boc-C14-COOH is a non-cleavable ADC linker used in the synthesis of antibody drug conjugates (ADC). ADC consists of antibodies connected to cytotoxins through ADC linkers for cancer treatment12.
PROTAC linker: Boc-C14-C00H is also an alkyl chain-based PROTAC linker used in the synthesis of PROTAC. PROTAC promotes the degradation of target proteins by simultaneously connecting the target protein and the ubiquitin ligase system12. Preparation method
The preparation of Boc-C14-COOH is usually carried out by the anhydride method, which includes esterification of hexadecanoic acid with anhydride acid, and then adding tert-butyl alcohol for alcoholysis to obtain the final Boc-C14-C00H product4.

Storage conditions
Boc-C14-COOH should be stored at room temperature.
