Introduction

Mercuric chloride (HgCl₂) is a chemical compound with a long legacy in scientific research, industrial manufacturing, and analytical chemistry. When produced as AR (Analytical Reagent) or ACS (American Chemical Society) grade, it meets the highest standards of purity and consistency, making it indispensable for laboratories, quality control, advanced manufacturing, and environmental science. With increasing regulatory scrutiny and demand for reliable reagents, understanding the nuances of mercuric chloride AR/ACS grade—from properties and uses to sourcing and safety—is more important than ever. This definitive guide from Brand Chemical Supplies delivers everything you need to make informed, compliant, and safe use of high-purity mercuric chloride.

Section 1: What is Mercuric Chloride AR/ACS Grade?

Chemical Identity and Grades

Mercuric chloride (HgCl₂) is a white, odorless, crystalline compound highly soluble in water and various organic solvents. “AR grade” refers to Analytical Reagent grade, a global standard for laboratory chemicals, ensuring high purity and minimal impurities. “ACS grade” is certified by the American Chemical Society, meeting or exceeding their stringent specifications for reagent chemicals.

Key Data:

Chemical Formula: HgCl₂
Molecular Weight: 271.50 g/mol
Appearance: White crystalline powder or granule
Solubility: 7g/100mL in water at 20°C; also soluble in alcohol and ether
Melting Point: 277°C (530°F)
Boiling Point: Sublimes at 302°C (575.6°F)
Purity: ≥99.5% (AR/ACS grades)
Grades: AR (Analytical Reagent), ACS (meets ACS specifications), Technical (lower grade)

Why AR/ACS Grade?

Consistency: Batch-to-batch uniformity is paramount in analytical, research, and industrial applications.
