L-Lysine Hydrochloride CAS 657-27-2

L-Lysine Hydrochloride CAS 657-27-2 is the monochloride salt of the essential amino acid L-lysine , chemically defined as (S)-2,6-Diaminohexanoic acid monohydrochloride, functioning primarily as a limiting amino acid supplement in animal feed premixes and a nutritional fortification agent in food processing. Also known as L-Lysine HCl or Lysine monohydrochloride, this crystalline powder is utilized to optimize protein synthesis in livestock diets and serves as a precursor in the fermentative production of pharmaceutical intermediates. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

Product Description

What is L-Lysine HCL?

L-Lysine HCL is the hydrochloride salt form of L-Lysine. Why do we use the salt form? Because pure Lysine is unstable and difficult to handle. By binding it with hydrochloric acid, we create a stable, crystalline powder that is highly soluble, easy to digest, and has a long shelf life.

It is the most cost-effective way to supplement this crucial amino acid that the body cannot produce on its own.

Physicochemical Properties

For procurement managers and R&D teams, consistency in the spec sheet is everything. Here are the key technical parameters:

Key Application Fields

1. Animal Feed (The Powerhouse Sector) This is where L-Lysine HCL is king. Corn and soy-based diets are naturally deficient in Lysine.

  • Swine: Crucial for lean muscle deposition and weight gain.
  • Poultry: Essential for meat yield and egg production.
  • Aquaculture: Increasingly used to reduce reliance on expensive fishmeal.
  • The Benefit: By adding L-Lysine HCL, farmers can use lower-cost plant proteins while still achieving maximum growth rates.

2. Human Nutrition & Supplements In the nutraceutical market, Lysine is often paired with Vitamin C for immune support. It is also a staple in sports nutrition for tissue repair and collagen synthesis.

3. Food Industry Used as a flavor enhancer and a nutritional fortifier in bread, noodles, and rice products to improve the protein profile of grain-based foods.

Why Texture and Granularity Matter

Not all Lysine is manufactured equally. One of the biggest complaints in production is dust.

Poorly manufactured L-Lysine HCL creates excessive dust in the mixing facility, which is a health hazard and leads to product loss. We focus on supplying a product with a consistent particle size distribution. This ensures:

  1. Better Flowability: It moves through hoppers and mixers without bridging.
  2. Homogeneity: It mixes evenly into the feed or supplement premix, ensuring every dose or pellet has the exact right amount of amino acid.

Safety and Precautionary Measures

While L-Lysine HCL is a feed/food grade product, it is handled in industrial quantities, so safety protocols must be followed.

  • Inhalation: The dust can be a mild respiratory irritant. Facility staff should always wear dust masks (N95) during hooping or mixing operations.
  • Contact: Prolonged contact with skin may cause mild irritation. Wear protective gloves and long sleeves.
  • Eyes: If dust enters the eyes, flush immediately with water. Safety goggles are recommended in the mixing zone.

Recommended Storage Conditions

L-Lysine HCL is relatively stable, but it can degrade if treated poorly.

  1. Humidity Control: It is slightly hygroscopic (absorbs moisture). Bags should be kept on pallets, off the floor, in a dry environment.
  2. Temperature: Store in a cool, well-ventilated area, away from direct sunlight.
  3. Packaging Integrity: Once a bag is opened, it should be used quickly or resealed tightly to prevent caking.

FAQ - Technical & Supply Chain

  • Q:

    Does CAS 657-27-2 cover all forms of Lysine available in the feed market?

    A: No. CAS 657-27-2 specifically designates L-Lysine Monohydrochloride (HCl), which is a high-purity crystalline salt (typically >98.5%). It does not cover L-Lysine Sulphate (typically a 70% fermentation complex) or Liquid Lysine base, which possess different chemical structures, impurity profiles, and CAS registry numbers.
  • Q:

    Is L-Lysine Hydrochloride suitable for use in water-soluble veterinary powder formulations?

    A: Yes. Unlike the sulfate form which contains insoluble biomass residues, L-Lysine Hydrochloride (CAS 657-27-2) is fully water-soluble. This physical property makes it the intended grade for manufacturing clear liquid feed supplements or water-soluble veterinary medicated powders where complete dissolution is required to prevent nozzle clogging.
