Calcium Chloride, Dihydrate (ACS Grade) from LabChem Inc. is a versatile, high-purity crystalline salt essential for precise analytical and biological applications. Meeting the stringent standards of the American Chemical Society (ACS), this reagent ensures minimal background interference, making it ideal for sensitive chemical synthesis and electrolyte solution preparation. Unlike the anhydrous form, the dihydrate (CaCl2 - 2H2O) is a stable, granular solid that is easy to weigh accurately. It serves as a primary source of calcium ions (Ca2+) and is frequently used in molecular biology to prepare "competent cells" for DNA transformation.

Description

Overview

Lead Times May Vary.

The product's primary benefit is its versatility and controlled form. Calcium Chloride Dihydrate (CaCl₂ · H₂O) is a stable, easily weighed material, making it convenient for preparing precise standard solutions, buffers, and media components. It is widely used as a desiccant (drying agent) and as a source of calcium ions (Ca²⁺) for promoting cell competence or in chemical synthesis. Manufactured by LabChem Inc., this product provides a trustworthy and dependable foundation for your analytical needs.

Features:

Precise Reagent Prep: The stable dihydrate form prevents rapid moisture absorption during the weighing process, ensuring highly accurate molar concentrations for standard solutions and buffers
Effective Desiccant: Widely used in drying tubes and desiccators to maintain an anhydrous environment for moisture-sensitive samples
Cell Competence: A critical component in "Heat Shock" transformation protocols, where Ca²⁺ ions stabilize the cell membrane to allow for the uptake of plasmid DNA
Analytical Reliability: ACS certification guarantees the removal of trace heavy metals and impurities that could catalyze unwanted side reactions

Laboratory Safety & Handling:

IMPORTANT! Exothermic Reaction: Dissolving Calcium Chloride in water releases significant heat. Always add the salt slowly to the liquid while stirring to manage the temperature rise safely.

Hygroscopic Nature: Even as a dihydrate, this salt will continue to pull moisture from the air. Keep the container tightly sealed in a cool, dry location.
Personal Protection: ACS Grade Calcium Chloride can cause serious eye irritation. Always wear safety goggles and gloves. In case of contact, flush immediately with plenty of water.

Please refer to the Safety Data Sheet (SDS) for complete handling and safety information.
