2,2,14,14-四甲基-8-氧代-十五烷二酸二乙酯 (CAS No.738606-43-4)

Product Name:Diethyl 2,2,14,14-tetramethyl-8-oxopentadecanedioate

English Name:Diethyl 2,2,14,14-tetramethyl-8-oxopentadecanedioate

CAS No.:738606-43-4

Aliases:Diethyl 8-oxo-2,2,14,14-tetramethylpentadecanedioate, 2,2,14,14-Tetramethyl-8-oxopentadecanedioic acid diethyl ester

Molecular Formula:C23H42O5

Physical Properties:Colorless to light yellow transparent oily liquid with a characteristic ester odor. Relative density approximately 0.96 g/cm³ (20°C), boiling point approximately 150-160°C (0.1 mmHg). Insoluble in water, readily soluble in common organic solvents such as ethanol, diethyl ether, acetone, and ethyl acetate. Generally stable to acid, base, and oxidizing agents, but susceptible to hydrolysis or decomposition under prolonged high temperature or strongly alkaline conditions.

Uses:This product serves as an organic synthesis intermediate. It can be used to prepare pentadecanedioic acid derivatives bearing 8-hydroxy or 8-oxo functional groups via hydrolysis, reduction, and other reactions, and is an important precursor for hindered aliphatic diacids and bifunctional linking units. Due to the sterically hindered ester groups at both ends, it is commonly used in intermediates for polymer materials, fine chemicals, and pharmaceutical synthesis.
