Pigment Yellow 13

Pigment Yellow 13 is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pigment Yellow 13 rather than just read about it. In short: Pigment Yellow 13 is an organic compound and an azo compound. It is a widely used yellow pigment.

Key takeaways

Pigment Yellow 13 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pigment Yellow 13 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pigment Yellow 13 from memory before moving on to harder problems.

Reference excerpt

Pigment Yellow 13 is an organic compound and an azo compound. It is a widely used yellow pigment. It is also classified as a diarylide pigment, being derived from 3,3'-dichlorobenzidine.

Production and characterization Pigment Yellow 13 is produced industrially by tetrazotization of 3,3′-dichlorobenzidine, followed by azo coupling with acetoacetylated Xylidine.

Properties Pigment Yellow 13 is a combustible, low-flammability yellow solid that is practically insoluble in water. It decomposes upon heating above 330 °C. The crystal structure consists of a layered arrangement with space group P-1 (space group no. 2). Pigment Yellow 13 is closely related to Pigment Yellow 12, wherein the two xylyl groups are replaced by phenyl and to Pigment Yellow 14 where the xylyl groups are replaced by o-tolyl. It is often depicted as an azo (-N=N-) structure, but according to X-ray crystallography closely related compounds exist as the keto-hydrazide tautomers.

Use Pigment Yellow 13 is used as a pigment, primarily in offset printing.

Worked examples

Example 1 — a first encounter with Pigment Yellow 13

Start with the simplest possible case. Write down what Pigment Yellow 13 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pigment Yellow 13 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pigment Yellow 13 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pigment Yellow 13

In research: Pigment Yellow 13 appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pigment Yellow 13 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pigment Yellow 13 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Diarylide pigments, Organic pigments, Pigments, so understanding it makes those chapters shorter.
In everyday life: Look for Pigment Yellow 13 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
