Pharmaceutical intermediates are the chemical building blocks used in the multi-step synthesis of active pharmaceutical ingredients (APIs). This guide explains what they are, why quality matters, and how to source them responsibly. What are pharmaceutical intermediates? An intermediate is a compound produced partway through the synthesis of a finished API. They range from simple building […]

Every laboratory relies on a core set of reagents and inorganic chemicals. This guide introduces some of the most common laboratory reagents and what they are used for. Essential laboratory reagents Sodium hydroxide — a strong base for pH adjustment, titration and synthesis. Hydrogen peroxide — a versatile oxidiser for cleaning, disinfection and reactions. Silver […]
Acids are among the most heavily used chemicals in industry — essential for processing, manufacturing and treatment. This guide covers the main industrial acids, their applications and how to handle them safely. The major industrial acids Hydrochloric acid — metal pickling and cleaning, pH control, and chemical synthesis. Sulfuric acid — the most-produced industrial chemical; […]
Solvents are the workhorses of chemistry — and choosing the right one can be the difference between a clean, efficient process and a failed one. This guide walks through the key properties to weigh when selecting a solvent for extraction, synthesis or cleaning. Key properties to consider Polarity — “like dissolves like”: polar solvents dissolve […]
Sodium hydroxide (NaOH), also known as caustic soda or lye, is one of the most important industrial chemicals — a strong alkali used everywhere from manufacturing to water treatment. This guide covers its properties, grades and main applications. What is sodium hydroxide? Sodium hydroxide is a white solid alkali (supplied as beads, flakes or pearls) […]
Buying chemicals online is convenient, but in a market that includes unverified sellers it pays to know what to look for. This guide explains how to buy chemicals safely from a regulated EU supplier — and the documentation and compliance you should expect. 1. Check the supplier is a registered company A trustworthy supplier publishes […]
Chemical labels often carry terms like “reagent”, “ACS”, “USP” or “technical” grade. These grades describe purity and the standards a chemical meets — and choosing the right one is essential for getting reliable results without overpaying. Here is a clear explanation. Why purity grade matters The same chemical compound can be sold at very different […]
Hydrogen peroxide (H₂O₂) is a powerful, versatile oxidising agent used across cleaning, disinfection, water treatment and chemical synthesis. It is sold in several concentrations and grades, and choosing the right one matters for both performance and safety. This guide explains the main hydrogen peroxide grades and where each is used. How hydrogen peroxide works Hydrogen […]
Acetone (CAS 67-64-1) is one of the most widely used solvents in the world — a clear, colourless, fast-evaporating liquid valued for its ability to dissolve a broad range of organic compounds. This guide covers what acetone is used for across industry and the laboratory, the grades available, and how to source it reliably. What […]
