2-Amino-2-methyl-1-propanol | CAS 124-68-5 | 95% Purity | Sterically Hindered Tertiary Amino Alcohol | pH Adjuster, Pigment Dispersant, Buffering Age

1. Product Overview

2-Amino-2-methyl-1-propanol (AMP), with CAS number 124-68-5, is a sterically hindered tertiary amino alcohol with the molecular formula C₄H₁₁NO and a molecular weight of 89.14 g/mol. Commercially known as AMP-95, this versatile compound is a clear, colorless to pale yellow liquid with a mild ammonia-like odor. It is fully miscible with water and soluble in common polar organic solvents such as ethanol, acetone, and glycol.

AMP is widely recognized for its multifunctional performance as a pH adjuster, pigment dispersant, buffering agent, and chemical intermediate. Its unique molecular structure, featuring both an amino group and a hydroxyl group, makes it an indispensable additive across coatings, personal care, metalworking, water treatment, and pharmaceutical industries.

2. Key Features and Advantages

• Excellent pH Buffering Capacity — pKa of 9.7 at 25°C provides strong alkalinity and stable pH control in aqueous systems, typically maintaining pH within the 9.0–10.5 range.

• Multifunctional Versatility — Combines pH adjustment, pigment dispersion, thickening enhancement, corrosion inhibition, and biostability in a single additive.

• Low Volatility & Low Odor — High boiling point (165°C) and low vapor pressure (<1 mmHg at 25°C) minimize VOC emissions and ammonia odor compared to traditional amines.

• High Water Solubility — Fully miscible with water, ensuring easy incorporation into aqueous formulations.

• Compatibility — Compatible with a wide range of resins, polymers, and surfactants, making it suitable for diverse formulation systems.

• Non-VOC Status (EPA) — Recognized by the U.S. EPA as a negligibly reactive compound, exempt from VOC regulatory requirements under the Clean Air Act.
