Methyl D-Lactate CAS 17392-83-5

What Methyl D-Lactate Is

Methyl D-lactate is the methyl ester of D-lactic acid with the formula C4H8O3, a colorless to pale yellow clear liquid with a slight characteristic odor. Lactic acid carries a stereocenter, so methyl lactate is sold as three defined items: the D or (R)-(+) ester (CAS 17392-83-5), the L or (S)-(-) ester (CAS 27871-49-4) and racemic methyl lactate (CAS 547-64-8). Produced from bio-based lactic acid, the ester is miscible with water and with alcohols, ethers and ketones, is readily biodegradable and has lower volatility than many conventional solvents. UATChem supplies both solvent grade and high-enantiopurity chiral grade, with assay and enantiomeric excess reported on the COA for each lot so buyers can match the solvent or synthesis job.

Green Solvent and Chiral Synthesis Use

• Industrial and electronic cleaning. Metal, precision and electronic cleaning and paint stripping, replacing halogenated, NMP and petroleum solvents with a biodegradable ester.
• Coatings, inks and agrochemicals. Carrier and coalescing solvent for coatings and printing inks, and a solvent in emulsifiable or soluble liquid crop formulations.
• Chiral synthesis. The defined R enantiomer works as a chiral building block or resolving intermediate for pharmaceutical and agrochemical active ingredients.
• Flavor and personal care. Mild lactate ester solvent in flavor work and in cosmetic and personal care formulations.

Typical Specifications

Solvent grade and high-enantiopurity chiral grade differ in assay and enantiomeric excess; both figures are reported on the COA, while the physical constants below identify methyl D-lactate.

Packaging, Documents and Ordering

• Packed in 25 kg and 200 kg drums and in IBC totes, with bulk tankers on request; drums and totes stay sealed in a cool, ventilated place away from heat and ignition sources as a flammable liquid.
• Every lot carries a TDS and COA with assay, enantiomeric excess, water content and appearance, together with an SDS; sample bottles for solvent or chiral evaluation can be arranged.
• For a quote, UATChem needs the grade (solvent or high-enantiopurity chiral), quantity, packing and destination port.

FAQ

Q: What is methyl D-lactate used for?

A: It is a bio-based ester solvent for cleaning and coatings; the R enantiomer is a chiral building block for pharma synthesis.

Q: What is the difference between methyl D-lactate and L-lactate?

A: D is the (R)-(+) ester, CAS 17392-83-5; L is the (S)-(-) ester, CAS 27871-49-4; racemic methyl lactate is CAS 547-64-8.

Q: Is methyl D-lactate a bio-based green solvent?

A: Yes, it is made from bio-based lactic acid, biodegradable and water miscible, replacing halogenated and petroleum solvents.
