L-Tyrosine Disodium Salt Dihydrate (CAS 122666-87-9) Product Introduction

L-Tyrosine Disodium Salt Dihydrate is a high-purity and highly water-soluble derivative of L-tyrosine. Compared with conventional L-tyrosine monomer, this sodium salt form significantly improves water solubility and exhibits superior solution stability, eliminating the low-solubility limitation in aqueous systems.

Serving as a critical amino acid additive for cell culture media, the product is widely utilized in biopharmaceutical manufacturing processes, including monoclonal antibody production, recombinant protein expression and vaccine fermentation. With low endotoxin content and stable batch consistency, it fully meets strict requirements for biotech research, pharmaceutical production and premium nutritional formulation applications.

Features & Benefits

- Excellent water solubility, dissolves rapidly and completely in aqueous solution without precipitation
- Higher biological availability than ordinary L-tyrosine, suitable for precision cell culture systems
- Low endotoxin, high purity and strict batch-to-batch stability
- Stable chemical properties, convenient for storage and industrial mass production
- Widely compatible with biopharmaceutical fermentation, biological research and nutritional synthesis scenarios!

1,3-Dihydroxyacetone (DHA)

1,3-Dihydroxyacetone (also known as DHA, glycerone, or 1,3-dihydroxy-2-propanone) is the simplest ketotriose (3-carbon ketose sugar) with the molecular formula C₃H₆O₃ and a molar mass of 90.08 g/mol.

Basic Properties

- Appearance: Hygroscopic, white crystalline powder with a sweet, cooling taste and a mild characteristic odor.
- Solubility: Highly soluble in water (>250 g/L at 20°C), ethanol, ether, and acetone.
- Melting Point: 75–80°C.
- Stability: Stable at pH 4.0–6.0; degrades in strongly alkaline conditions.
- Structure: Exists as a cyclic dimer in solid form; dissociates into a reactive monomer in aqueous solution. It has no chiral center, making it achiral.

Production

Commercially, DHA is primarily produced via microbial fermentation of glycerol using acetic acid bacteria (e.g., Gluconobacter oxydans). It can also be derived from plant sources like sugar beets and sugar cane.

Main Applications

1. Cosmetics (Sunless Tanning): The primary use of DHA is as the active ingredient in sunless tanning (self-tanning) products. It reacts with amino acids in the skin’s outer layer (keratin) via the Maillard reaction, forming brown pigments called melanoidins that darken the skin without UV exposure.
2. Food & Pharmaceuticals: Used as a food additive, a pharmaceutical intermediate, and in biodegradable polymer synthesis.
3. Biochemistry: As a key intermediate in carbohydrate metabolism (glycolysis) in plants and animals.

Safety

- FDA-approved for use in cosmetics and food .
