For any professional involved in chemical procurement, research, or manufacturing, understanding chemical specifications is fundamental. These seemingly simple lines of text on a product datasheet or supplier's website unlock critical information that directly impacts synthesis outcomes, product quality, and cost-effectiveness. Let's break down some common specifications using 2,3,4-Trifluorobromobenzene (CAS 176317-02-5) as an example.

Appearance: Clear liquid

This is perhaps the most straightforward specification, describing the physical state and visual characteristic of the compound at room temperature. 'Clear liquid' tells us that the substance is a liquid under standard conditions and lacks significant turbidity or visible particulate matter. For a product like 2,3,4-Trifluorobromobenzene, which is known to be a liquid with a relatively low boiling point, this specification is important. It helps in immediately identifying the substance and can be an initial indicator of quality – a deviation from this (e.g., a solid or cloudy appearance when it should be clear) might suggest degradation, contamination, or improper storage.

Assay: ≥98.0%

The 'Assay' specification is one of the most critical. It indicates the minimum purity of the desired chemical compound in the sample. For 2,3,4-Trifluorobromobenzene, an assay of '≥98.0%' means that at least 98.0% of the material is the target compound, with the remaining percentage consisting of impurities. The nature and quantity of these impurities are often just as important as the assay itself. Different applications may have varying tolerance levels for specific impurities. For instance, in pharmaceutical synthesis, even trace amounts of certain reactive byproducts could be detrimental. Researchers often need to buy 2,3,4-Trifluorobromobenzene with a high assay to ensure predictable reaction outcomes and to avoid downstream purification challenges.

CAS No.: 176317-02-5

The Chemical Abstracts Service (CAS) Registry Number is a unique numerical identifier for a chemical substance. It is universally recognized and eliminates ambiguity in chemical nomenclature, which can sometimes be complex or vary between regions. When you search for a specific compound to buy, using the CAS number is the most reliable way to ensure you are referencing the correct chemical. For example, when contacting a supplier about 2,3,4-Trifluorobromobenzene, quoting CAS 176317-02-5 ensures clarity and avoids confusion with isomers or similar compounds.

Molecular Formula: C6H2BrF3

This formula represents the exact number of atoms of each element present in a molecule of the compound. In this case, one molecule of 2,3,4-Trifluorobromobenzene contains 6 carbon atoms, 2 hydrogen atoms, 1 bromine atom, and 3 fluorine atoms. This information is crucial for stoichiometry calculations in chemical reactions and for understanding the compound's basic chemical composition.

Molecular Weight: 210.98

Derived from the molecular formula and the atomic weights of its constituent elements, the molecular weight is essential for quantitative analysis and reaction calculations. It allows chemists to accurately weigh out the correct molar quantities needed for synthesis. For any manufacturer or buyer of 2,3,4-Trifluorobromobenzene, knowing this value is fundamental for precise process control.

Understanding these specifications empowers procurement managers and R&D scientists to make informed decisions. When you choose to purchase 2,3,4-Trifluorobromobenzene, engaging with a supplier like us, who transparently provides accurate specifications and adheres to quality standards, is a cornerstone of successful chemical sourcing.
