What is Methyl D-Lactate CAS 17392-83-5?

Methyl D-Lactate is the methyl ester of D-lactic acid, also named (+)-Methyl D-lactate, Methyl (R)-lactate, or D-lactic acid methyl ester. It has the molecular formula C4H8O3, CAS 17392-83-5, and EINECS 241-420-6.

What does the D or R designation mean for Methyl D-Lactate?

The D/R designation identifies the chiral configuration of the lactate unit. This enantiomer is used when an optically active intermediate is required for chiral drug, agrochemical, or fine-chemical synthesis.

What optical purity is typically available for Methyl D-Lactate?

Commercial chiral grades are commonly specified at about 98% ee or higher, with many suppliers offering D/(D+L) optical content of 99% or more. The exact value is batch-dependent and should be confirmed for the selected grade.

What are the key physical properties of Methyl D-Lactate?

It is a clear colorless liquid with a mild ester odor, a boiling point around 144-145 deg C, and a density near 1.09 g/mL. It is miscible with water and many common organic solvents.

What are the main applications of Methyl D-Lactate?

It is mainly used as a chiral building block in pharmaceutical and agrochemical synthesis, as a biodegradable solvent or cleaner, and as an intermediate for D-lactic acid and poly(D-lactic acid) derivatives.

Why is moisture control important when storing Methyl D-Lactate?

As an ester, prolonged contact with moisture can cause hydrolysis into lactic acid and methanol. It should therefore be kept in tightly sealed, dry containers and stored away from strong acids, bases, and oxidizing agents.
